2xy+17b=13bd Solve for b,d,x and y; and why can't I type this equation into my computer and get the answer ?

Question

Use college algebra.
And since the origional IBM computers that were DOS only systems when we were in high school in 1986 would solve this equation just by typing it in and now computers are supposedly better then why can't you solve this equation with a desktop computer and to top it all of you can't even buy a program that solves algebraic equations?

Answer 1

Mathematica will solve complex equations:

... but even the Students edition costs over $100.

Answer 2

in the beginning, you will would desire to split up the plus/minus so as which you get 2 equations. Secondly, there are 2 strategies you're able to try this. you could the two placed parentheses around the numerator (the stunning component of the fraction) or you could split the denominator and upload 2 fractions. the 2d way is a lot much less intuitive for many, so I won't advise it. Thirdly, you attempt to take the sq. root of a damaging selection. collectively as achievable, I doubt (in case you're asking considered one of those question), you opt to be doing this. i'm guessing you attempt to do the quadratic formula. whilst the selection below the sq. root, the discriminant (b^2 - 4ac) is damaging, you will have not any genuine ideas. it incredibly is fairly achievable which you have imaginary ones. yet, like I reported, I a manner or the different doubt you care approximately those. Fourthly, i'd in basic terms enter the equation into Google's seek bar (it incredibly is a calculator too in case you probably did no longer comprehend!). i'd type the two like so: (8 + sqrt(-20))/6 and (8 - sqrt(-20))/6 the main important downside (for my section) of doing it like it incredibly is that Google will placed issues in decimal variety, no longer fraction variety. it incredibly isn't any longer undesirable for purposes, yet would be iffy whilst speaking approximately hardcore math issues. Google's calculator is incredibly smart adequate to evaluate your imaginary component of the sq. root and return a complicated selection (a selection which has the two a real and an imaginary section).

Answer 3

2 xy + 17 b = 13 bd
solving b
17 b - 13 bd = -12 xy
b = - 12 xy / (17 - 13 d)

solving d
13 bd = 12 xy + 17 b
d = ( 12 xy + 17 b ) / (13 d )

solving x
2xy = 13 bd - 17 b
x = ( 13 bd - 17 b ) / 2y

solving y
2xy = 13 bd - 17 b
y = ( 13 bd - 17 b ) / 2x

check again your DOS IBM computer for the same problem you just presented. Does it solve the problem
try to ask other persons near your area this.

Conclusion: the computer just can not solve the algebraic problem unless a certain programmer (a person) will do the solution program for you

Answer 4

solving for b

2xy + 17b = 13bd

Transpose 13bd

2xy + 17b - 13bd = 13bd - 13bd

2xy + 17b - 13bd = 0

2xy + b(17 - 13d) = 0

Transpose 2xy

2xy + b(17 - 13d) - 2xy = 0 - 2xy

b(17 - 13d) = - 2xy

Divide (17 - 13d) from both sides of the equation

b(17 - 13d) / (17 - 13d) = 2xy / (17 - 13d)

b = 2xy / (17 - 13d)

- - - - - - - -

Solving for d

2xy - 17b = 13bd

2xy + 17b / 13b = 13bd / 13b

2xy + 17b / 13b = d

- - - - - - - - - - - - - -

Solving for x

2xy + 17b = 13bd

Transpose 17b

2xy + 17b - 17b = 13bd - 17b

2xy = 13bd - 17b

2xy / 2y = 13bd - 17b / 2y

x = 13bd - 17b / 2y

- - - - - - - - - - -

Solving for y

2xy + 17b = 13bd

Transpose 17b

2xy + 17b - 17b = 13bd - 17b

2xy = 13bd - 17b

2xy / 2x = 13bd - 17b / 2x

y = 13bd / 2x

- - - - - - - -s-

Answer 5

2xy+17b=13bd

for b:
2xy+17b=13bd
17b - 13bd = -2xy
b(17 - 13d) = -2xy
b= (-2xy) / (17 - 13d)

for d:
13bd = 2xy+17b
d= (2xy+17b) / 13b

for x:
2xy+17b = 13bd
2xy = 13bd - 17b
x= (13bd - 17b) / 2y

for y:
2xy+17b=13bd
2xy = 13bd - 17b
y = (13bd - 17b) / 2x

holy ****....i just got a huge headache
