2x = -8

• x = -4
• x = 4
• x = -10
• x = 6

-48 = -6a

• a = -8
• a = 8
• a = 42
• a = -42

-8 - b = -8

• b = 4
• b = -16
• b = 16
• b = 0

What is the first step in solving this equation:
5x + 7 = 12

• Divide by 5
• Subtract 5
• Multiply by 7
• Subtract 7

Solve:
3(x - 2) = 18

• 6.7
• 4
• 8
• -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
