Question

Solve the inequality.

−78≤m−138
The solution is

Answer 1

M = 60

Explanation:

You are doing the opposite to each side to simplify the inequality so on one side it is the variable in your case, it is m and the other side is your number. You are going to add 138 to both sides and then you get your answer.

-78 ≤ M - 138

-78 + 138 ≤ M - 138 +138

60 ≤ M

=

M ≥ 60

Answer 2

m=60
You add 138 to both sides
