Math Solving Equations

An inverse operation is

• reversing the sign in an inequality

• using the opposite operation to solve equations

•  A number’s distance from zero

Solve:
19  +  a  =  –40

• –950

• –59

• –31

• 2.6

Solve:
x – 8 = –5 

• 13

• –13

• 3

• –3

Solve:

• 20

• 7

• 10

• 3

Solve:
6b = 30

• –24

• 24

• 180

• 5

Solve:

• 152

• 176

• 5

• 27

Like terms are 

• numbers or same variable raised to the same power

• equal numbers

• only unknown values

One difference between equations and expressions would be...

• you solve both of them using inverse operations.

• you flip the symbol when you multiply or divide by a negative

• equations have an equals because they show two equal expressions. Expresions have terms and operations.

14+3x=26

• x=6

• x=1

• x=4

• x=3

3x+7=-6x-56

• x=-7

• x=-5

• x=3

• x=7
