What is the first step in solving the equation 2a - 4(a - 5) = 10

• Add 4 to both sides
• Add the 2a and a 
• Distribute 4 to a and -5
• Distribute -4 to a and -5

8v - 4(v + 8) = 8

• 2
• 10
• 4
• -4 

22 + 2a = 37 + 6 + a

• 21
• -21
• 5
• 6

The goal of solving a one, two, or multi-step equations is to:

• Find the constant

• Find the coefficient
