Question

Billy has a gift card with a $150 balance. He buys several video games that cost $35 each. After the purchases, his gift card balance is $45. Write an equation to help find out how many video games Billy bought.

Answer 1

Has a total of $150
Video games are $35 each
Final balance is $45

150 - 35x = 45

To solve the equation:
150 - 35x = 45
150(-150) - 35x = 45(-150)
-35x = -105
-35x/-35 = -105/-35
x = 3

Answer 2

150-35x=45 is the answer
