Addison was given a gift card for a coffee shop. Each morning, Addison uses the card to buy one cup of coffee. Each cup of coffee costs $3 and after buying 4 cups of coffee, the card had a $3 remaining balance. Write an equation for A, A, in terms of x, x, representing the amount money remaining on the card after buying xx cups of coffee.

A=−3x+15

Step-by-step explanation:

answer: l

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
