Carmen collects music boxes. She currently has 7 and plans to collect 3 more each year. She wants to know how long it will take her to collect 28 music boxes. Which equation matches Carmen's situation?

• 7 + 3x =28

• 3(7) - x = 28

• 28x + 7 = 3

• 7x + 3 = 28

33 = 4a - 7

• a=-10

• a=10

• a=4.5

• a=-4.5

-3a + 8 = 14

• a= -2
• a= -7.5
• a= 2
• a= 6

Solve for x.

 $\frac{1}{3}x-\frac{3}{7}=\frac{4}{7}$  

• 3

•  $\frac{1}{3}$  

•  $\frac{9}{7}$  

• -3

Solve for the variable. $\frac{1}{3}x+6=-8$  

• 42

• -42

• 6

• -6
