Solve:
12 - 7x = 12x - 22x + 39

• 1
• -27/17
• -1
• 9

Solve:
5(x - 2) - 8x = -8 + 2x + 13

• 1
• 11/5
• -3
• 31/11

Solve:
2(4x - 3) - 8 = 4 + 2x

• x = 5/3
• x = 3
• x = 1
• x = 2

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides
• Subtract 11 from both sides
• Add 11 to both sides
• Divide 3 on both sides.

A gymnastics center charges a $60 registration fee and $15 per class. Olivia registers to take a class and pays a total of $210. Which equation can be used to determine how many classes Olivia signed up for?  

• 60 - 15x = 210 
• 15x - 60 = 210
• 15x + 60 = 210 
• 210 + 15x = 60
