Creating Objective Equations

You bought a $5 magazine and four

erasers. You spent a total of $25. How

much did each eraser cost?

• 5+x=25

• 4x + 5 = 25

• 5x = 25

• 5x + 4 = 25

Scott works on cars. He charges $35 for each car plus $7 per hour. Write an equation that represents this scenario if Kylie's car bill was $63.

• 7x + 35 = 63

• 7x = 63

• 7x - 35 = 63

• 35x + 7 = 63

Five less than twice a number is equivalent to 47. 

• 5 - 2x = 47 

• 2x - 5 = 47 

• 5x - 2 = 47 

• 2 - 5x = 47 

What is the solution to 
-3x+2< 8

• x > -3

• x > -2

• x < -2

• x < -3

Mr. Roast buys 2 lb of turkey and 12 lb of ham.  The total cost is $30.  The ham costs $2 per lb.  
Create an equation to find the cost of 1 lb of turkey.

• 2y + 12x = Romero

• 2x + 12(2) = 30

• 30 + 2x = 12(2)

• 12(2) = 2x

Solve for x:

-3(2x - 1) = 30

• x = - 6.2

• x = -4.5

• x = -3.8

• x = - 6.9

Which equation has x = 5 as the solution?

• x + 15 = 10

• 2x = 5

• 2x = 10

• x/2 = 10
