2 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. It typically involves addition or subtraction followed by multiplication or division.

Front

Solve for a: 15 = 2a + 7

Back

a = 4

Front

Solve for a: 20 = 2 - a

Back

a = 18

Front

Solve for x: 3x - 5 = 22

Back

x = 9

Front

Solve for x: 2x + 10 = 110

Back

x = 50

Front

What is the first step in solving the equation 2x + 3 = 11?

Back

Subtract 3 from both sides to isolate the term with the variable.

Front

What is the second step in solving the equation 2x = 8?

Back

Divide both sides by 2 to solve for x.

Front

If x + 4 = 10, what is x?

Back

x = 6

Front

If 5x = 25, what is x?

Back

x = 5

Front

What does it mean to isolate a variable in an equation?

Back

Isolating a variable means to manipulate the equation so that the variable is on one side and all other terms are on the opposite side.
