Algebra Equations Variables on Both Sides

What is the next step to solve for x?

• + 2x to both sides; -7 = 8x - 29x

• + 2x to both sides; -7 = 10x - 31

• - 2x to both sides; -7 = 8x - 33x

• - 2x to both sides; -7 = 6x - 31

What is the next step to solve for x?

• - 10 to both sides; 3x = 30

• - 10 to both sides; 3x = 50

• - 3x to both sides; 10 = 37x

• - 40 to both sides; 3x = -30

If you choose to distribute -2 to BOTH 2x and - 7, what is the next step of the eqation?

• x/5 + 10 = -4x + 14 + 17

• x/5 + 10 = -4x - 7 + 17

• x/5 + 10 = 4x - 7 + 17

• x/5 + 10 = -4x - 14 + 17

What is the next step to solve for x?

• x = 5(-4x + 21)

• x = (-4x + 21)/5

• 6

• -6

• -1

• 3
