One Step Math Equations

Solve for x:

• x = 20

• x = 7

• x = 10

• x = 3

x ÷ 2 = 12

• x = 24

• x = 6

• x = 20

• x = 10

The area of a rectangular deck is 125 square feet. The width of the deck is 25 feet. Write an equation and solve to find the length.

• 25x=125,
  x = 5 feet

• x+22=125,
  x = 20 feet

• x-25=125
  x=150 feet

• 25x=125
  x=3,125 feet

Which equation has x = 5 as the solution?

• x + 15 = 10

• 2x = 5

• 2x = 10

What is the correct step to solve for the variable?
15 = m - 5

• add 15 to both sides

• add 5 to both sides

• subtract 15 from both sides

• subtract 5 from both sides

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
