Equations with Variables on Both Sides

Where is the first mistake?

• Subtracting 3 on both sides

• Distributing the 9

• Subtracting 9x on both sides

• Inequality error

Solve:
30 + 6t = 11t

• 3

• 5

• 6

• 30

Solve:
10x + 9 = 4x - 9

• 0

• 3

• -3

• -18

Solve:
8w - 8 = -4w + 16

• 8

• 16

• 24

• 2

Solve:
7w + 5 = 3w - 15

• 5

• -2

• 2

• -5

Solve the equation:
4x - 5x + 9 = 5x - 9

• x = -3

• x = 9

• x = 3

• x = -9

What is the next step you should take?

1 + 4n = 10 - 14n

• Collect the variables (letters) to the left

• add 1 from both sides

• subtract 14n to both sides

What is the final answer to

10 + 2n = 8n - 2n + 10 ?

• 12

• 5

• 0

• -15

What is the next step you should take?

14x + 8 = -3 - 7x

• Collect the variables (letters) on the left side

• multiply -7 to both sides

• add 14x to both sides

• subtract 7x to both sides

What is the final answer to

4(x - 2) = -3 + 5x

• 2

• -10

• -5

• -3
