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 how they appear in the equation.

Front

Solve for a: -3a + 8 = 14

Back

a = -2

Front

What is the first step to solve the equation: 11 - 3x = 44?

Back

Subtract 11 from both sides.

Front

Solve for a: 33 = 4a - 7

Back

a = 10

Front

What is the purpose of using inverse operations in solving equations?

Back

Inverse operations help to cancel out terms and isolate the variable.

Front

Solve for x: 2x + 4 = 10

Back

x = 3

Front

What does it mean to 'balance' an equation?

Back

Balancing an equation means keeping both sides equal by performing the same operation on both sides.

Front

Solve for x: 7x + 3 = 23

Back

x = 3.

Front

What is the second step in solving the equation: 11 - 3x = 44 after subtracting 11?

Back

Divide both sides by -3.
