i have an substitution grid and i dont know what A will equal if one of the answers equal to 155

x+2y=4 3x-4y=-3

X+2y=11 3x-4y=-17

2x-y=6 x+y=6

A=4B A-B=9 (Same problem)

y=4x 3x-y=1

y=-2x-8 -4x-y=24

How do I do this problem using the substitution method. x - 9y = -66, -x - 5y = -46

1)  y=-5x+2      y=3x-14   2)  x+y=0      5x+y=4

y=x+1 y=2x+2     x+y=5 2x-3y=5       x+y=0 5x+y=4
