What is -8(-8x-6)=-6x-22 ?

x=-1

Step-by-step explanation:

-8(-8x-6)=-6x-22

Distribute

64x +48 = -6x -22

Add 6x to each side

64x+6x +48 = -6x+6x -22

70x +48 = -22

Subtract 48 from each side

70x +48-48 = -22-48

70x = -70

Divide  by 70

70x/70 = -70/70

x=-1

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
