Solve by using a system of two equations in two variables. (Show your work) A father, being asked his age and that of his son, said, "If you add 4 to
my age and divide the sum by 4, you will have my son's age. But 6 years ago I was 7 1/2 times as old as my son.” Find their ages.

135 is your answer

step-by-step explanation:

try 180 times three then divide that number by 4 (sides) to get your answer. im glad to : )

also, thx a lot for the points : )

0.32

step-by-step explanation:

2.24/7

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
