Dirk sold 7 more than 2 times as many gym memberships this month than last month. This month he sold 43 memberships. Question 1 Part A Use arithmetic to find the number of memberships Dirk sold last month. Enter the correct answers in the boxes.

x is variable or an unknown value to find

example:

2x = 5 which means x = 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
