Solving One Variable One Step Equations

Linda ordered 6 boxes 0f pepperoni pizza and b boxes of vegetarian pizza.  Which one of the following equations can you use to find the value of b the number of boxes of vegetarian pizza?  

• b x 6 = 18

• 6 + b = 18

• b - 18 = 6

In the equation x + 7 = 12, 7 is being added to the variable, x. How should you show your work to isolate the variable and solve the equation?

• Subtract 7 from both sides. The solution is x = 5.

• Add 7 to both sides.

  The solution is x = 19.

• Multiply both sides by 7 The solution is x = 84.

For which equation is b=4 a solution?

• 4b=1

• b/2=8

• b+4=0

• b-14=-10

• subtract

The variable, k, is being divided by 11. How should you show your work to isolate the variable?

• Divide both sides by 11

• Multiply both sides by 11.

• Add 11 to both sides.

• Subtract 11 to both sides.

Which equation has w = 8 as the solution?

• 8w= 64

• 16w = 240

• 16 - w = 9

• 4 + w = 10

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
