What is the value of x?

Thank you!

l don't know the answer of that

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
