Jada is collecting stickers. After getting 15 more stickers, she has 60 stickers in total.

Select all the equations Jada can solve to find , the number of stickers she started with.

• x + 15 = 60

• x - 15 = 60

• x = 60 +15

• x = 60-15

• 15x=60

Solve the equation.

p + 12 = 17

Solve the equation.
 $\frac{1}{3}s=7$
