Alexandra had $24 to spend on seven pencils. After buying them she had $10. Find the equation that matches this situation.

• 24 - 10 = 7x

• 7x - 24 = 10

• 7x + 10 = 24

• 10 + x =14

331 students went on a field trip to Valleyfair. Six buses were filled and 7 students traveled in cars. How many students were in each bus? Find the equation that matches this situation.

• 331 = 7x + 6

• 331 = 13x

• 331 = 6x + 7

• 331 - 7 = 6x

Ava bought a $5 magazine and four

erasers. You spent a total of $25. How

much did each eraser cost?

Find the equation that matches this situation.

• 5 + x = 25

• 5 + 4x = 25

• 5x = 25

• 23 - 5 = 4x

• yes

• no

5x + 6 = 71

• x = 12

• x = 11

• x = 13

• x = -12

19h - 7 = 23 + 14h

• h= -6

• h = 6

• all real numbers

• no solution
