Apastry chef created a 40-ounce sugar solution that was 28% from a 20% sugar solution and a 40% sugar solution .how much of the 20% sugar solution and how much of the 40% sugar solution were used [2.3]

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

answer: group b.

step-by-step explanation:
