Answer:
1. -8+3x
2. 51x-2+4x2 (squared)
3. 66x +324
4. 6x+2
5. 13 +13x
Step-by-step explanation:
I don't think I really understand the question but I tried to simplify the equations
5x-9y=-65
10x-3y=20
Multiple the first equation by 2
10x-18y=-130
10x -3y=20
Then subtract the two equations to get rid of the x
21y=-150
Divide the -150 by 21
Y=-7.14
Plug the y into the original equation. (Either one)
5x-9(-7.14)=-65
5x-64.28=-65
Then add 64.28 to the -65
5x=-0.72
Divide by 5
X=-0.144
I hope this is right
