Equations and Inequalities

By Courtney Tout

Multiple Choice

What is the goal of solving equations and inequalities?

To get all the numbers on one side of the symbol

To isolate the variable

To use inverse operations to graph

To make math difficult

Step 1: Use Inverse to Undo Constants

Step 2: Use Inverse to Undo Coefficient

Step 3: Plug in and Check

Two Step Equations

Multiple Choice

3c + 5 = 23

c = 3

c = 6

c = 7

c = 18

Multiple Choice

What is the first step to solve this equation:
11 - 3x = 44

Add 3 to both sides

Subtract 11 from both sides

Add 11 to both sides

Divide 3 on both sides.

Multiple Choice

Level 3

Identify the steps to solve for b

Add 6 to both sides and 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

Subtract 6 from both sides then divide both sides by 5

Multiple Choice

$5x-1=19$

$x=4$

$x=10$

$x=5$

$x=15$

Multiple Choice

$\frac{x}{4}+8=10$

$x=-4$

$x=-8$

$x=8$

$x=16$

Multiple Choice

20 = 2 - a

a= 18

a= -18

a= -10

a= 12

Multiple Choice

The steps in solving 5b - 6 = 24 are:

Add 6 to both sides and 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

Subtract 6 from both sides then divide both sides by 5

Multiple Choice

13= 5m -2

-3

-2

Multiple Choice

4x + 7 = 23

x = 16

x = 4

x = 9

x = 12

Multiple Choice

6p - 5 =13

-3

Exact same process as Equations

Only Difference:

If you multiply or divide by negative number you must FLIP the Inequalitiy SYMBOL

--> Negative Numbers in front of the variable do this.

Two Step Inequalities

Multiple Choice

Find the solution

$X\ge4$

$X\le4$

$X\ \le\ 10$

$X\ >\ 4$

Multiple Choice

Find the solution

$X\ \le\ 6.5$

$X\ >2$

$X\ \ge\ 10$

$X\ \le\ 10$

Multiple Choice

16 - 4a > 8

a<-2

a>-2

a<2

a>2

Multiple Choice

Do I need to flip my sign?
-3x ≥ 12

Yes

Multiple Choice

Do I need to flip my sign?
3x ≥ 12

Yes

Graphing Inequalities

Multiple Choice

When you graph an inequality, you use a closed dot when you use which symbols?

≤, ≥

<, >

Multiple Choice

When graphing an inequality, you use an open dot when you use which symbol?

<, >

≤, ≥

Multiple Choice

When graphing b < 6 would you use an open or closed circle?

Open

closed

Multiple Choice

When graphing b < 6 would you use the arrow point left or right?

Left

Multiple Choice

Match the graph with its inequality.

b > –2

b < –2

b ≥ –2

b ≤ –2

Multiple Choice

What inequality does the number line graph represent?

x ≤ -4

x ≥ -4

x < -4

x < 4

Multiple Choice

Match the graph with its inequality.

a > 11

a < 11

a ≥ 11

a ≤ 11

Multiple Choice

Choose the correct graph that best describes the solution for each inequality
5 + x ≥ 29

Multiple Choice
