One, Two, and Multi-Step Equations

Which choice models this situation?
Taylor has read 125 pages in a book. The book has a total of 262 pages. How many pages does she have left to read to finish the book?

• p - 125 = 262

• p + 125 = 262

• 125p = 262

• p/125 = 262

2 (n + 5) = -2 The first step in solving the following equation is ____________

• add five to both sides

• distribute 2 to all terms in the parenthesis

• add 2

There were 331 students that went on a field trip. Six buses were filled and 7 students traveled in a van. How many students were on each bus?

• 6 + 7x = 331

• 331 - 6x = 7

• 6x + 7 = 331

• 6x + 7y =331

Which choice models this situation? At Pierce County Middle School, there are 5 art classes with 24 students in each class. How many students altogether are in the art classes?

• s - 5 = 24

• s + 5 = 24

• 5s = 24

• s/5 = 24

Solve for w.

-6w + 1 = -11

• 2

• 1.2

• 12

• -2

Solve for t.

-4 = 2t - 2

• -1

• 1

• 4

• 0

What is the next step to solve this equation?
3x - 5 = 7

• Add 5 to both sides of the equation

• Add 3x to both sides of the equation

• Subtract 5 from both sides of the equation

• Subtract 7 from both sides of the equation

What will the equation look like after you combine like terms?

• -5x + 5 = 35

• x + 5 = 35

• 5x + 5 = 35

• -x + 5 = 35

Where/what is the mistake?

• Line 2 - You should add 12 to both sides.

• Line 4 - You should divide both sides by 2/3.

• Line 4 - You should multiply both sides by the original fraction.

• Line 5 - There was a calculation error.

What should you do first to figure out what "z" is?

• Subtract 4 from both sides.

• Divide both sides by 4.

• Multiply both sides by 4.

• Add -36 to both sides.
