Crystal has a coupon for off the regular price of ice cream. Which expression shows the amount of money saved on ice cream with a regular price of d dollars?

Let original amount be x

Let amount on coupon be y

Therefore, amount saved is x-y

E.g if the ice cream is originally 10 dollars, and the coupon is 2 dollars, she spends 8 dollars, hence saving 2 dollars

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
