Group our variables 20m and 30m subtract 30m from both sides 20m + 100 - 30m = 30m + 80 - 30m
Cancel 30m on the right side:
-10m + 100 = 80
Group constants
Group our constants 100 and 80. subtract 100 from both sides -10m + 100 - 100 = 80 - 100
Cancel 100 on the left side:
-10m = -20
Divide each side of the equation by -10
-10m
-10
=
-20
-10
m = 2
Final Answer
m = 2
What is the Answer?
m = 2
