Answer:
[tex]m=-\frac{39}{80}[/tex]
Step-by-step explanation:
we have
[tex]\frac{2}{5}=2m+\frac{11}{8}[/tex]
Solve for m
That means ----> Isolate the variable m
Multiply both sides by 40 to remove the fractions
Note: 40=(8)(5)
[tex](40)\frac{2}{5}=(40)2m+(40)\frac{11}{8}[/tex]
[tex]16=80m+55[/tex]
subtract 55 both sides
[tex]16-55=80m\\-39=80m[/tex]
Divided by 80 both sides
[tex]m=-\frac{39}{80}[/tex]
