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 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.

Front

Solve for g: 3g - 1 = 2

Back

g = 1

Front

Solve for x: x + 7 = 10

Back

x = 3

Front

Solve for A: A - 9 = 6

Back

A = 15

Front

Solve for b: 4 - 2b = 2

Back

b = 1

Front

Solve for R: R + 9 = 10

Back

R = 1

Front

What does it mean to isolate a variable?

Back

Isolating a variable means to manipulate the equation so that the variable is on one side and all other terms are on the other side.

Front

What is the first step to solve the equation x + 5 = 12?

Back

Subtract 5 from both sides to isolate x.

Front

What is the principle of equality in equations?

Back

The principle of equality states that if you perform the same operation on both sides of an equation, the two sides remain equal.
