4a3a = (4 + 3)a2-5 = 7a?
What’s wrong with this equation somone plz help

a = -1

Step-by-step explanation:

4a3a = (4+3)2-5 = 7a

12a = 14a - 5 = 7a

12a = 14a - 5 - 7a = 0

12a -14a + 5 + 7a = 0

(12 - 14 +7)a + 5 = 0

5a + 5 = 0

5a = -5

a = -1

i don't know if its right or not

(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).

hope i
