In the equation below, what could the first step be?
-4(10m+5)=12

• Add 5 to both sides
• Subtract both sides by 5
• Add 4 to both sides
• Divide both sides by -4

In the equation below, what could be ANOTHER first step to solve?
-4(10m+5)=12

• Distribute the -4 to each term inside the parentheses
• Divide both sides by 12
• Multiply both sides by 4
• Add 10m and 5

In the equation below, which step has to come first?
.5(2c + 10) + 4c = -12

• Combine 2c and 4c
• Multiply .5 by 4c
• Divide both sides by 2
• Multiply .5 by 2c and 10

You solved the equation below and got m=2. What would the substitution step look like?
5(3m+1)-6m=23

• 5(32+1)-62=23
• 5(3(2)+1)-6(2)=23
• 5(6+1)-12=23
• 5(3(2)-1)+6(2)=23
