Question

Solve for m:

2/5=2m+11/8

Enter your answer as a fraction, like this: 42/53

Answer 1

`m=-(39)/(80)`

Explanation:

we have

`(2)/(5)=2m+(11)/(8)`

Solve for m

That means ----> Isolate the variable m

Multiply both sides by 40 to remove the fractions

Note: 40=(8)(5)

`(40)(2)/(5)=(40)2m+(40)(11)/(8)`

`16=80m+55`

subtract 55 both sides

`16-55=80m\\-39=80m`

Divided by 80 both sides

`m=-(39)/(80)`
