Answer:
m=11÷600
Step-by-step explanation:
150m-100m+47.750=50.5000-200m
collect the like terms
-50m+47.75=50.5-200m
move variable to the left side and change its sign
-50m+200m+47.75=50.5
Move constant to the right side and change its sign
50m+200m=50.5-47.75
collect the like terms(again)
150m=50.5-47.75
subtract the numbers
150m=2.75
divied both sides of the equation by 150
m=11÷600
solution
m=11÷600
alternative form
m=0.0183
