WRITE AN EQUATION

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

WRITE AN EQUATION 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
