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 the inverse operations in the reverse order of how they appear in the equation.

Front

Solve for x: -3x + 5 = -13

Back

x = 6

Front

Solve for a: 6 - 3a = 21

Back

a = -5

Front

Solve for x: -4x + 1 = 21

Back

x = -5

Front

Solve for y: 4y + 1 = 13

Back

y = 3

Front

Solve for a: 15 = 2a + 7

Back

a = 4

Front

What is the first step to solve the equation 2x + 3 = 11?

Back

Subtract 3 from both sides to get 2x = 8.

Front

What is the second step to solve the equation 2x = 8?

Back

Divide both sides by 2 to get x = 4.

Front

What does it mean to 'balance' an equation?

Back

Balancing an equation means performing the same operation on both sides to maintain equality.
