Match each equation to the first step needed to solve the equation.

• Multiply by 4

• -9 = -4 - 5x

• Divide by 4

• 12 = 4x

• Combine like terms

• Add 4

• 2x - 8 + 4x = 8

• Subtract 4

• 13 = -3x + 4

Find the error in the problem below
19 - 2k = 3k - 1
     +3k   +3k
19 + 1k = -1
-19           -19
k = -20

• They should have divided by 1 for the last step
• They should add 19 instead of subtracting 19
• I can not find an error
• Instead of adding 3k they should subtract 3k
