8+x=32. The monthly fee is $8, it is fixed so there is no variable since you are solving for this month only. solve for x to see how much each rental costs.

cp123 · Answer

oops i meant 6x, since she rented 6 movies for an undefined price.

cp123 · Answer

8+6x=32. Now solve for x. so you need to isolate x on its own. start by subtracting 8 from each side. 6x=24. Now, since 6 is being multiplied by x, you need to divide both sides by 6.

cp123 · Answer

So, since 24/6=4, x=4. She pays $4 for each movie she rents.

cp123 · Answer

To check the answer, replace 4 in the original equation for x. 8+6(4)=32. 8+24=32. 32=32! this is a true statement, so the answer is correct
