Bob is comparing two Window-Washing Companies.  Clean Fast costs $15 plus $2 per window.  See Out costs $5 plus $3 per window.  Write an equation to find when both companies will cost the same. 

• 15x + 2 = 5 + 3x
• 15x + 2 = 5x + 3
• 15 + 2x = 5 + 3x
• 15 + 2x = 5x + 3

Solve for x.
3x + 2 = 6x - 7

• x = 9
• x = 3
• x = -3
• x = 7
