Question

Help with #6 pls!!! It's substitution with system of equations! I will fan and medal!!

Answer 1

First divide 8x-8y=-24 by 8 to get x-y=-3
Then add that to 3x+y=23 to isolate x
3x+y=23
X-y=-3
4x=20
x=5
Then plug in x to find the y value

Answer 2

Thank u so much!!

Answer 3

Welcome! :)

Answer 4

Which equation would I plug x in though?

Answer 5

@angeltears

Answer 6

Either one is fine

Answer 7

Would you like me to show you how?

Answer 8

So let's try to plug it into the second one
3x+y=23
3(5)+y=23
15+y=23
Subtract 15 on both sides
Y=8

Answer 9

8x-8y=-24
8(5)-8y=-24
40-8y=-24
Subtract 40 on both sides
-8y=-64
Divide by -8
Y=8
