Question

Josh has 27 new magazines to read. Let M be the number of magazines he would have left to read after reading R of them. Write an equation relating M to R . Then use this equation to find the number of magazines he would have left to read after reading 25 of them.

Answer 1

M=27-R
When R=25, solve for M
=27-25
M=2

Hope this helps!

Answer 2

27-R=M because 27 - the amount you read equals how much you have left
