Solve equations with variables on both sides

Solve the following equation

9 + 2a = -3 - 4a

• -2

• 2

• 5

• -1

Solve the equation:

3a - 24 = -a

• -8

• 6

• 12

• -12

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

1 + 4n - 6n = 1 - 8n

• subtract 8n to both sides

• combine the like terms 4n + -6n

• multiply 6n to both sides

What is the first step you could take?

1 + 4n = 10 - 14n

• Collect the variables (letters) to the left

• subtract 14n to both sides

• add 1 from both sides

• add 10 on both sides

What is the next step you could take?

-11x = -11

• add 11 to both sides

• divide both sides by 11

• subtract 11 from both sides

• divide both sides by -11

What is the next step you could take?

14x + 8 = -3 - 7x

• add 14x to both sides

• add 7x to both sides

• multiply -7 to both sides

• subtract 7x to both sides

Is -3 a solution to the equation:

10x + 9 = 4x - 9

• Yes

• No

• Maybe

Which equation represents for the picture?

• x + 8 = 12

• 2x = 4 + x

• 2x + 8 = 12 + x

• 2x + 2 = 3 + x
