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 the inverse operations in the reverse order of how they are applied.

Front

Solve for z: 0 = 8z + 8

Back

z = -1

Front

Solve for a: 26 = 5a + 1

Back

a = 5

Front

Solve for z: 9 = 2s + 1

Back

s = 4

Front

Solve for k: 2k + 12 = -4

Back

k = -8

Front

What is the first step to solve the equation 5x + 3 = 18?

Back

Subtract 3 from both sides to get 5x = 15.

Front

What is the second step to solve the equation 5x = 15?

Back

Divide both sides by 5 to get x = 3.

Front

What does it mean if an equation has no solution?

Back

It means that there is no value for the variable that can satisfy the equation.

Front

What is the solution to the equation 3y - 4 = 5?

Back

y = 3.
