Solving Equations

You will have a few questions on Solving Equations. Some with more steps than others. They will look like the following.

Multiple Choice

If 5x - 6 = -21, what value of "x" makes the equation true?

• x = -5.4

• x = -3

• x = 3

Multiple Choice

Solve the equation:

$$\frac{n}{5}+7=-5$$  

• n = -32

• n = 10

• n = -60

Multiple Select

What does the first step look like to solve this equation:

$$4\left(10+3x\right)=16$$  

• 40 + 12x = 16

• 40 + 3x = 16

• 12x + 10 = 16

• 40 + 12x = 64

Multiple Choice

What is the solution to this equation?

$$3x+2-x=2x+4$$  

• x = 1

• No Solution

Multiple Choice

Sandy has an acorn collecting contract that pays her a base rate of $200 per month and an additional $15 for each pound of acorns she gathers. Last month Sandy earned $275. Which equation represents how much Sandy made last month, if x represents the pounds of acorns?

• 200x - 15 = 275

• 200x + 15 = 275

• 15x + 200 = 275

Fill in the Blanks

How many pounds of acorns did Sandy gather using the equation:

$15x+200=275?$

Fill in the Blanks

Solve the proportion:

$\frac{a}{5}=\frac{14}{2}$  

Multiple Select

What would the first step be to solving this proportion (select all that apply):

$$\frac{5}{-2}=\frac{n-2}{6}$$  

• $$-2n+4=30$$  

• $$-2n-2=30$$  

• $$-2\left(n-2\right)=30$$  

Fill in the Blanks

Solve this proportion:

$\frac{6}{x+4}=\frac{12}{3x+1}$  

Now you get to try it on your OWN!!!

Be AWARE, Inequalities will be on there!!!
