Answer:
You would use long division and use work it out in your answer sheet. But the answer to that is 15
Step-by-step explanation:
X=4
explanation:
-reduce the fraction
-make the numerators equal
-divide both sides by 5
The answer to the question is a
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
