One-step Equations

What is a one-step equation?

An equation where you only need to do one operation to solve for x.

What is an operation?

addition
subtraction
multiplication
division

To solve a one-step equations, you need to use the INVERSE operation.

Inverse means opposite

Multiple Choice

What is the inverse (opposite) of addition?

Multiple Choice

What is the inverse (opposite) of subtraction?

Multiple Choice

What is the inverse (opposite) of multiplication?

Multiple Choice

What is the inverse (opposite) of division?

One-Step Equations

To solve a one-step equations, you need to use the inverse (opposite) operation.

Multiple Choice

How do you solve?

x+5=10

$-5\ on\ both\ sides$

$+5\ on\ both\ sides$

$\div5\ on\ both\ sides$

$\times5\ on\ both\ sides$

Multiple Choice

How do you solve?

x-3=4

$-3\ on\ both\ sides$

$+3\ on\ both\ sides$

$\times3\ on\ both\ sides$

$\div3\ on\ both\ sides$

Multiple Choice

How do you solve?

3x\equiv12

$+3\ on\ both\ sides$

$-3\ on\ both\ sides$

$\div3\ on\ both\ sides$

Solve for X

Multiple Choice

Solve:

x-3=12

$x=9$

$x=15$

$x=4$

Multiple Choice

Solve:

x+5=10

$x=5$

$x=15$

$x=50$

Multiple Choice

Solve:

3x=12

$x=9$

$x=15$

$x=4$

One-step equations multiplication and division

Students will solve one-step equations using multiplication and division

Remember

To solve a one-step equation: identify the operation in the equation, use the inverse operation on both sides to isolate the variable
To check the equation: rewrite the original problem, substitute the value for the variable, and simplify using order of operation

Multiple Choice

What is the operation in the equation?

\frac{m}{8}=6

multiplication

division

addition

subtraction

Multiple Choice

What inverse operation must be used in order to solve the equation?

\frac{m}{8}=6

multiplication

division

addition

subtraction

The operation in the equation is division
The inverse operation is multiplication
To solve, multiply both sides by the denominator
Reminder: Use parentheses to show multiplication

Multiple Choice

$9\ =\ \frac{a}{9}$

a = 18

a = 0

a = 1

a = 81

Multiple Choice

$\frac{a}{6}=0$

a = 60

a = 6

a = 0

a = 1

Multiple Choice

$\frac{x}{2}=6$

x = 4

x = 12

x = 3

x = 8

Multiple Choice

$\frac{x}{5}=3$

x = 15

x = 2

x = 8

x = 53

The operation in the equation is multiplication
The inverse operation is division
To solve, divide both sides by the coefficient
Reminder: Use fraction bar to show division

Multiple Choice

27 = 9a

a=3

a=36

a=18

a=9

Multiple Choice

6y = 24

y=18

y=4

y=6

y=3
