Question

6x-2y=32
4x-2y=18
solve?

Answer 1

can you make it so that one of these equations just looks like this? y = ____

Answer 2

Subtract the second equation from the first and solve for x

Answer 3

mathmate's approach would work as well you can subtract them and then you will know what x will be

Answer 4

i'm sorry but can someone walk me through?

Answer 5

ok, let's start by subtracting the second equation from the first:

6x-2y=32 ...(1)
4x-2y=18 ...(2)
(1)-(2)
6x-4x=32-18, =>
2x=14 =>
x=7

Now put x=7 in equation (1)
6(7)-2y=32
42-2y=32
2y=42-32=10
y=10/2=5
So x=7, y=5

Answer 6

hm

Answer 7

Is everything ok?
