Question

If-8x + 3y = 2 is a true equation, what would be the value of -32x + 12y?​

Answer 1

16

Explanation:

Answer 2

8

Explanation:

I started by just choosing a value for x and then a value for y that would make the first equation true. -1 for x and -2 for y worked...

`-8(-1)+3(-2)=2\\8+(-6)=2\\8-6=2\\2=2`

...so I used them in the second expression:

`-32(-1)+12(-2)\\32-24\\8`

Values that would make the 1st equation true will result in the second expression equally 8.
