• 0

-5 = 3m - 14

• 3
• -3
• 12
• -6.3

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.

The goal of solving two-step equations is to:

• francine
• Find the coefficient 
• Find the value of the variable

-4x+1=21

• x=120
• x=5
• x=30
• x=-5
