ANSWERS: Solving for y:

2x + 5y = -9 8x - y = -7

-8 (2x + 5y = -9) 2 ( 8x - y = -7 )

-16x - 3y = 72 16x - 2y = -14

-5y/-5 = 58/ -5

y = -11. 6

Solve for x:

2x = 5( -11.6) = -9

2x- 58 = -9 2x = -9 + 58 2x/2 = 49/2

x = 24.5

CHECK:

2 ( 24.5 ) + 5y = -9 49 + 5y = -9 5y = -9 - 49

5y/5= -58/5

y= -11.6

ANSWERS:

X = 24.5 y= -11.6
