How long would it take me to earn $139.50 of interest at 6% interest rate if i started with $930

the answer would be c:   ax + b = ax + c

step-by-step explanation:

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

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
