One Step Adding and Subtracting 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 does it mean to isolate a variable in an equation?

Back

Isolating a variable means to get the variable alone on one side of the equation, making it easier to solve.

Front

Solve the equation: n - 18 = 3

Back

n = 21

Front

Solve the equation: w + 6 = -2

Back

w = -8

Front

Solve the equation: y + 3 = -2

Back

y = -5

Front

Solve the equation: x + 40 = 56

Back

x = 16

Front

Solve the equation: 15 = n + 7

Back

n = 8

Front

What operation would you use to solve the equation x - 5 = 10?

Back

You would add 5 to both sides of the equation.

Front

What is the first step to solve the equation: 2n = 10?

Back

Divide both sides by 2 to isolate n.
