Equations Variable on Both Sides of Equation

What is the first step to solve this equations? 3n - 4 = -2 + 2n

• Add 2n to both sides of the equation

• Add 3n to both sides of the equation

• Subtract 2n from both sides of the equation

• Subtract 4 from both sides of the equation

What is the first step to solve this equation? 3x + 6 = 10 + 3x + 4x

• Add 4x to both sides of the equation

• Combine like terms 3x and 4x on the same side of the equation

• Add 3x and 6 to get 9x

• Add 6 and 10 to get 16

What is the next step to solve this equation?

3x + 6 = 10 + 7x

• Add 10 to both sides of the equation

• Add 6 to both sides of the equation

• Subtract 3x from both sides of the equation

• Add 7x to both sides of the equation

In order to solve an equation, we must get variables on side of an equation, and constants on the opposite side.

• True

• False
