Which number is the solution of m + 90 = 150?
The solution of m + 90 = 150 is 60.
To find the solution of the equation m + 90 = 150, we need to isolate the variable m.
Step 1: Subtract 90 from both sides of the equation:
m + 90 - 90 = 150 - 90
m = 60
Therefore, the solution to the equation is m = 60.
