Model and Solve Variables on Both Sides

Write the equation for the model.

• 2x - 2 = -x - 8

• -x - 2x = 2x - 8x

• -x - 2 = 2x - 8

Write the equation for the model.

• 3x + 1 = -x + 5

• -x + 1 = 3x + 5

• -x + x = 3x + 5x

Write the equation for the model.

• -x + 2 = 2x - 1

• -x + 2x = 2x - x

• 2x + 2 = -x - 1

Write the equation for the model.

• 3x + x = -x - 3x

• -x + 1 = 3x - 3

• 3x + 1 = -x - 3

Write the equation for the model.

• -2x - 1 = 2x - 9

• 2x - 1 = -2x - 9

• -2x - 9 = 2x - 1

Write the equation for the model.

• -x - 4 = 3x

• 3x + 4 = -x

• 3x - 4 = -x

Write the equation for the model.

• 2x - 4 = x - 7

• 2x + 4 = x + 7

• x - 4 = 2x - 7

Write the equation for the model.

• 2x + 7 = -3x + 2

• 2x - 2 = 3x - 7

• 2x + 2 = -3x + 7

Write the equation for the model.

• 2x + 3 = x + 1

• 2x + 1 = x + 3

• 2x - 1 = x - 3

• -x - 4 = 2x + 2

• -x - 2 = 2x - 4

• -x + 2 = 2x - 4
