3.2

Step-by-step explanation:

32x-1=16x+4

+1 .            +1

32x=16x+5

-16x   -16x

16x=5/5

3.2=x

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
