4a+2=3b-5 how do you solve?

Answer 1

4a+2 = 3b -5
4a = 3b-7
a= (3b -7)/4 thing is I need to know either a or b?

Dunno can't do it.

Answer 2

you will have 4a = 3b - 7.

The onlu option to solve is give adecuated values to constants a adn b. For example, if a = 0, then b = 7/3. The fisrt solution will be (0, 7/3)

Or if b = 0,then a = -7/3. The second solution will be (-7/3, 0)

Really, you will have infinite solutions of this system

Answer 3

4a+2=3b-5
4a-3b+7=0
4a-3b=-7
question what number when multiplied by 4 and what other number when multiplied by 3 will equal -7

a=-1 and b=1

Answer 4

Hi there , this equation is for a linear line on the coordinates because you dont have any of the variabes values you have to draw it . a is for X and b is for Y
make it like this
4x - 3y = -7
When ( x = 0 )
y = 2.3333
When ( y = 0 )
x = -1.75
This means on the X- y coordinates that the linear line cuts the X axis at -1.75 and cuts the Y axis at the 2.3333 and goes to infinity
so given any value of the two you will get the other .

hope i helped

Answer 5

a=(3b/4)-(7/4)

b=(4a/3)+(7/3)

Are you sure there isn't a second equation? We could give a numeric answer if you had one.

Answer 6

If you want to find a solution for both a and b (a numerical solution, rather than just a simplified solution like some of the other people posted), you will need two different equations. If you were only given one equation, then all you can do is simplify it.

Answer 7

-3b to both side,
-2 to both side
than you get
4a-3b = -3

thats it!!
you cant go any far

Answer 8

You can't, as you need 2 equations to solve for 2 variables.

Answer 9

Actually it is 1 equation in 2 unknowns.
So it has INFINITE SOLUTIONS.
For example (1,-1)
( 3n-1 , 4n +1 ) Is general solution for any value of n

Answer 10

4a+2=3b-5

4a-3b=-5-2

4a-3b=-7 add(-2+-5)

4a/-3b=-7/-3b *-3b

4a=-7

i hope i am right
