Question

X=2y-8
-4x+3y=7
Use substitution to solve the system. Please someone help me out

Answer 1

y = 5 x = 2

Explanation:

-4(2y - 8) + 3y = 7 Plug the first equation into the second equation and distribute the -4

-8y + 32 + 3y = 7 Combine like terms

-5y + 32 = 7

- 32 - 32 Subtract 32 from both sides

-5y = -25

y = 5

Plug 5 into the first equation as y

x = 2(5) -8

x = 10 - 8

x = 2
