x^2+3x-18
Step-by-step explanation: hoped I helped
Money spent at grocery store = x, money spent at game store = y
x = 24
x = 2y - 6
24 = 2y - 6
24 + 6 = 2y
30 = 2y
30/2 = y
15 = y <=== spent 15 at game store
2x+x=36
Kim's Sister age
2x+x=36 Add "x and 2x"
3x=36 Divide both sides by 3
÷3 ÷3
x=12
Kim's sister is 12 years old

Multiply that by two to get Kim's age
12•2=24 Kim is 24 years old.
