One-Step 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 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 steps to solve, typically involving two different operations to isolate the variable.

Front

Solve for y: -4y = 48

Back

y = -12

Front

Solve for x: x - 8 = -5

Back

x = 3

Front

Solve for x: 3x - 7 = 32

Back

x = 13

Front

Solve for a: 33 = 4a - 7

Back

a = 10

Front

Solve for c: 3c + 5 = 23

Back

c = 6

Front

What does it mean to isolate a variable?

Back

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

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.
