Solve 1-Step Addition Subtraction Inequalities

What inequality represents the following statement:

Four more than a number is more than 13.

• 13 > n + 4

• n + 13 > 4

• 4 > n + 13

• n + 4 > 13

Using the "opposite operation" to "undo" and isolate the variable when solving an equation is more commonly called...

• Inverse operations

• math

• variable

• PEMDAS

17 = x + 3

• x = 20

• x = 14

• x = 13

• x = 19

x - 32 = 49

• x = 17

• x = 71

• x = 81

• x = 49

x - 62 = 123
How should you show your work to isolate the variable and solve the equation?

• Add 62 to each side. 

• Subtract 62 from each side.

• Multiply each side by 62.

• Add 123 to each side.

When you solve one and two step equations and inequalities, whatever you do to one side you have to...

• one side

• both sides

• you can't solve equations and inequalities

What equation matches this situation?
Robyn had some video games then bought 4 more.  Now she has a total of 10 games.

• v - 4 = 10

• v + 4 = 10

• 10 - 4 = v

• Answer not Given

What is the first step in solving the following problem? 2x+10=22

• Multiply by 10

• Subtract 10 from each side

• Divide by 2

• Add 10 to each side

Solve.

• x ≤ 12

• x ≥ 14

• x ≥ 12

• x ≥ 23

• Subtract 6 from both sides then divide both sides by 5.

• Add 6 to both sides and multiply both sides by 5.

• Subtract 6 from both sides then multiply both sides by 5.

• Add 6 to both sides and divide both sides by 5.
