Question

Polly and Molly are writing letters to all of the athletes they love most. They have a list of 15 athletes, and Polly has already written 2 letters. Molly has written 4 letters. Write an equation with the variable (L) to determine how many letters they have left to write. You do NOT need to solve this equation.

Answer 1

15- (4+2)=L you can use this equation

Answer 2

Answer: L = 15 -2-4

Explanation:

Hi, to answer this question we have to subtract the letters that they have already written (2 and 4) to the total number of letters they have to write (15). That expression must be equal to the number of letters they left to write (L)

Mathematically speaking

L = 15 -2-4
