What is the first step you should take to solve this problem?

-3 ( x - 2 ) = -8 + 9x

• add 8 to both sides

• subtract 9b from both sides

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

• infinitely many solutions

• no solutions
