Solving and Graphing Linear Equations and Inequalities

Solve:
6x+10>5x-12

• x>2

• x<2

• x<-22

• x>-22

Solve:
3(x - 2) < 2(x + 9)

• x<24

• x>12

• x<12

• x>24

Does the given value make the inequality true? 
 x + 9 > 21, when x = 15

• True

• False

Translate the following phrase: Tom can spend no more than 20 dollars on his mom's birthday present.

• t > 20

• t < 20

• t ≤ 20

• t ≥ 20

In order to solve an equation, we must get variables on side of an equation, and constants on the opposite side.

• True

• False

3x + 2(4x - 4) = 3

• x = 4

• x = 3

• x = 2

• x = 1

What is the first step you should take to solve this equation:

 3(x-2)=2x+7

• Add 2 to both sides

• Isolate the variable on one side

• Use distributive property to get rid of the parentheses

• Subtract 7 from both sides

After using distributive property on the equation presented below, what will be your next step?

 3(x-2)=2x+7

• Add -6 to both sides

• Isolate the variable on one side

• Use distributive property to get rid of the parentheses

• Combine like terms and placing the similar terms on the same side

What would be the solution for the equation?

 3(x-2)=2x+7

• x = 13

• x = 5

• x = 1

• x = 13 /5

Select the equations that are true

• 3x-6=10+3

• 5x-3=10+5

• 4x-3=9+9x

• 14x -2 = 12
