Sorry but I need help once again.. -w-

1:x=10

Step-by-step explanation:

Step 1: Add 5 to both sides.

2/5x-5+5+-1+5

2/5x=4

Step 2: Multiply both sides by 5/2.

(5/2)*(2/5x)=(5/2)*(4)

x=10

answer: 48

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
