Jacob solved the following equation using the steps shown.

Step 1 5x + 9 = 2x - 3

Step 2 3x + 9 = -3

Step 3 3x = -12

Step 4 x = -4

What operation did he perform to get from Step 1 to Step 2?

• Subtracted 2x from both sides of the equation

• Subtracted 9 from both sides of the equation

• Multiplied both sides of the equation by 3

• Added -3 to both sides of the equation

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.

4k + 24 = 6k -10

• k = 17

• k =-17

• k= 5

• k = 1/5

11z - 5 = 9z + 7

• z= 6

• z = -6

• z = 1/6

• z =-1/6

Which step has the mistake?

• Step 1

• Step 2

• Step 3

• No mistakes

Solve: 5x + 15 = 10x - 40

• x = 10

• x = -10

• x = 11

• x = -11
