Solving Equations Difficult

An inverse operation is

• reversing the sign in an inequality

• using the opposite operation to solve equations

•  A number’s distance from zero

Choose the first step in solving the following equation.
-3y - 12 = 14

• add 3 from both sides

• add 12 to both sides

• subtract 12 from both sides

Solve:
x – 8 = –5 

• 13

• –13

• 3

• –3

Solve:
6b = 30

• –24

• 24

• 180

• 5

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.

Which of the following has an equals sign?

• Equation

• Expression

How do we solve f - 12 = -4

• add -12 to both sides

• subtract 12 from both sides

• add 12 to both sides

• add 4 to both sides

How do we solve -2k = -100?

• multiply by 2 on both sides

• divide by 2 on both sides

• add 100 to both sides

• divide by -2 on both sides

z/4 = -8

• z = -32

• z = 32

• z = 2

• z = -2

7 + g = 11

• g = 4

• g = -4

• g = 18

• g = -18
