Solving Equation Variables on Both Sides

What is the next step to solve this equation?

n - 4 = -2

• Add 4 to both sides of the equation

• Add n to both sides of the equation

• Subtract n 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

What is the next step to solve this equation?

-4x + 6 = 10

• Subtract 6 from both sides of the equation

• Add 6 to both sides of the equation

• Add 10 to both sides of the equation

• Subtract 4x from 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

What is the first step in solving the equation 2a - 4(a - 5) = 10

• Add the 2a and a 

• Add 4 to both sides

• Distribute +4 to the a and -5

• Distribute -4 to a and -5

What is the first step you should take to solve this equation: 3(x-2) = 2x + 7

• Add 2 to both sides

• Use the distributive property to get rid of the parentheses

• Isolate the variable on one side

• Subtract 7 from both sides

Solve the equation:

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

• 4

• 3

• 2

• 1

• x = 8

• x = 0

• x = 9

• x = 4

What is the second step in solving a Multi-Step Equation with variables on both sides.

• Distribute

• Combine like terms on each side of the equal sign

• Move the variable

• Solve for the variable
