Answer 1

Answer:

One month of gameplay costs $15

Step-by-step explanation:

Angie: 20 + 3x

Kenny: 20 + 2x

(20 + 3x) + (20 + 2x) = 115 --- add their costs together

(20 + 20) + (3x + 2x) = 115 --- collect like terms

40 + 5x = 115 --- simplify

5x = 75 --- subtract 40 from both sides

x = 15 --- divide both sides by 5
