What is 10x+8y = 100?

Answer 1

There is no single value for x or y. Still, we can solve for both.

10x+8y=100 <-lets get rid of the multiplier of x, divide by 10
x+0.8y=10 <-now lets get x alone, subtract 0.8y
x=10-0.8y <-this equation defines x

10x+8y=100 <-lets get a single y, divide by 8
1.25x+y=12.5 <-again, get y alone, subtract 1.25x
y=12.5-1.25x <-this equasion defines y

Since x and y are not single values but instead equasions, this is the best you can do. Plug in whatever values you want for y in order to come up with what x will have to be to fit your original equasion, and vice versa.

Answer 2

x=2 y=10

Answer 3

10x+8y=100
10x=100-8y
10/10x=100/10 - 8/10 y
x=10- 8/10 y

then replace the x with that new equation

Answer 4

x = 2, y = 10
x = 6, y = 5

Answer 5

you have to find x and y
If x = 4 wt is y .. you have to find that and you have to graph it

if x=1
----------
10x+8y = 100
= 10*4 + 8y = 100
= 40 + 8y = 100
= 8y = 100 - 40
= 8y = 60
= y = 7.5

now see if x=1
y = 7.5

now you write it like this (1,7.5)
its called ordered pairs

you have to fined more .. like if x=2 , x=3 , x=4 , x=5

now you have to graph it ( x comes first and then y)

Answer 6

The only thing you can do with that equation is write it in standard linear form:

8y = 100 - 10x

y = (100/8) - (10/8)x

Answer 7

X=6
Y=5

Answer 8

As it stands, with no additional information about either x or y, there are multiple answers. For example, x=10 and y=0, or x=6 and y=5.

Answer 9

Hi my name is Bob,
Your answer I beleive is 9 2/10 or 9 1/5


see ya

Answer 10
