Solving One and Two-Step Equations

Front

What is a one-step equation?

Back

A one-step equation is an equation that can be solved in a single step, typically by performing the same operation on both sides to isolate the variable.

Front

What is a two-step equation?

Back

A two-step equation is an equation that requires two operations to isolate the variable, usually involving addition or subtraction followed by multiplication or division.

Front

Solve for z: 144 = 12z

Back

z = 12

Front

Solve for a: 19 + a = -50

Back

a = -69

Front

Solve for k: 3k + 5 = 23

Back

k = 6

Front

Solve for x: x + 3 = 13

Back

x = 10

Front

Solve for b: 6b = 30

Back

b = 5

Front

What is the first step to solve the equation 2x + 4 = 12?

Back

Subtract 4 from both sides to isolate the term with the variable.

Front

What does it mean to isolate a variable?

Back

To isolate a variable means to manipulate the equation so that the variable is on one side by itself, making it easier to solve.

Front

What operation would you use to solve the equation x/4 = 3?

Back

Multiply both sides by 4 to isolate x.
