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

Solve for a: 2a + 4 = 10

Back

a = 3

Front

Solve for x: x/12 - 8 = -4

Back

x = 48

Front

What is the first step to solve the equation 3x + 5 = 14?

Back

Subtract 5 from both sides to isolate the term with x.

Front

Solve for x: 9 + 3x = 10

Back

x = 1/3

Front

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

Back

To isolate a variable means to get the variable alone on one side of the equation.

Front

Solve for x: x/7 - 2 = 8

Back

x = 70

Front

What is the second step to solve the equation -6w + 1 = -11?

Back

Subtract 1 from both sides, then divide by -6.

Front

Solve for w: -6w + 1 = -11

Back

w = 2

Front

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

Back

Inverse operations are used to undo operations and isolate the variable.
