Joseph used the problem-solving strategy Work Backward to solve the inequality 2n+5<13. Shawnee solved the inequality using the algebraic method. Compare the two methods.

Question

THANK YOU!

Answer 1

2n + 5 < 13
2n < 13-5
2n < 8
n < 4

any other method only complicates and confuses the problem.
I have no idea what this "problem-solving strategy Work Backward" is.
