Question

7x - 5y = 6
-8x + y = 12

anyone knows how to do it? (:

Answer 1

yup

Answer 2

Multiply the second equation by 5 then add the equations together

Answer 3

can you show me the steps? :)))

Answer 4

You can do that, or you can do this:

7x - 5y = 6
-8x + y = 12

y = (6 - 7x)/-5
y = 12 + 8x

y = y
-5(12 + 8x) = 6 - 7x

-60 - 40x = 6 - 7x
33x = -66
x = -66/33
x = -2
y = -4

Answer 5

Those are the steps if you set y = y

Answer 6

and what would be "x"?

Answer 7

got it! thank you!!!!!!!!
