Solving Three Step Equations

Front

What is a three-step equation?

Back

A three-step equation is an algebraic equation that requires three operations to isolate the variable and solve for its value.

Front

What is the first step in solving the equation 7x - 3x - 8 = 24?

Back

Combine like terms: 7x - 3x becomes 4x, so the equation simplifies to 4x - 8 = 24.

Front

How do you isolate the variable in the equation 4x - 8 = 24?

Back

Add 8 to both sides of the equation: 4x = 32.

Front

What is the final step to solve for x in the equation 4x = 32?

Back

Divide both sides by 4: x = 8.

Front

What is the solution to the equation 2x - 3 + 4x = 27?

Back

x = 5.

Front

What is the first step in solving the equation 2x - 1 = ¾x + 9?

Back

Subtract ¾x from both sides: 2x - ¾x - 1 = 9.

Front

How do you combine like terms in the equation 2x - ¾x - 1 = 9?

Back

Combine 2x and -¾x to get 1.25x - 1 = 9.

Front

What is the next step after combining like terms in 1.25x - 1 = 9?

Back

Add 1 to both sides: 1.25x = 10.

Front

How do you solve for x in the equation 1.25x = 10?

Back

Divide both sides by 1.25: x = 8.

Front

What is the solution to the equation -2x - 7 + 3x = 10?

Back

x = 17.
