Im getting kicked out of school petrolyn motor oil is a combination of natural oil and synthetic oil. it contains 8 liters of natural oil for every 5 liters of synthetic oil. if 456 liters of natural oil are used, how many liters of petrolyn oil will be made?

the answer is 62.8 cubic units

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
