Solving Two Step Equations

Front

What is a two-step equation?

Back

A two-step equation is an algebraic equation that requires two operations to solve for the variable.

Front

How do you isolate a variable in a two-step equation?

Back

To isolate a variable, perform inverse operations in the reverse order of operations.

Front

What is the first step to solve the equation: 2t - 2 = -4?

Back

Add 2 to both sides to get 2t = -2.

Front

What is the second step to solve the equation: 2t = -2?

Back

Divide both sides by 2 to find t = -1.

Front

Solve the equation: 4c - 6 = 2.

Back

Add 6 to both sides to get 4c = 8, then divide by 4 to find c = 2.

Front

What does it mean to check your solution in an equation?

Back

To check your solution, substitute the value back into the original equation to see if it holds true.

Front

Solve the equation: 3n + 4 = 7.

Back

Subtract 4 from both sides to get 3n = 3, then divide by 3 to find n = 1.

Front

What is the solution to the equation: 8 = 4v + 12?

Back

Subtract 12 from both sides to get 4v = -4, then divide by 4 to find v = -1.

Front

Solve the equation: 0 = 8z + 8.

Back

Subtract 8 from both sides to get 8z = -8, then divide by 8 to find z = -1.

Front

What is the inverse operation of addition?

Back
