HELPPP I DONT GET THISSS

Sally collects art work. She has 21 pieces of art so far. She buys two pieces of art every month. Set a variable and write an equation to find out how many months does it take for her to have 35 pieces of art work.

Answer 1

It will take 7 months.

Explanation:

Let m represent the number of months.

21 + 2m = 35

Then, isolate the variable.

2m = 35 - 21

2m = 14

m = 7

Answer 2

2x + 21 = 35
