Solving Equations with Variables on Both Sides

Solve: 4k + 39 = 7k + 6

• k = 11

• k = 3

• k = -3

• k = -11

Solve: 14y + 5 = 8y - 1

• y = 1

• y = -1

Solve: 5k + 21 = 17k - 3

• k = -2

• k = 2

• k = 1.5

• k = -1.5

Solve: 15y + 5y - 6 = 17y

• y = 2

• y = -2

• y = 9

• y = -31

3x + 10 + 2x = 2 (x + 8)

5x + 10 = 2x + 16

What is the next step? Drag the correct part under the equation. Be sure to put the one labeled left on the left.
