9(-2y-8)-3y=-156

how would i answer this question?

y = 4

Step-by-step explanation:

9(-2y-8)-3y=-156

-18y-72-3y = -156

-21y = -156+72

-21y = -84

-y = -84 / 21

-y = -4

y = 4

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
