What is the 1st step in solving the following equation? 3x + 7 = x - 21

• Move variables to same side

• Add 7 to both sides

• divide both sides by 3

• Subtract 21 from both sides

What is the 2nd step in solving the following equation?

3x + 7 = x - 21

2x + 7 = -21

• Divide both sides by 2

• add 7 to both sides

• Subtract 7 from both sides

• Subtract 21 from both sides

• x=3

• x=2

• x=-2

• x=1
