Question

Find the value of m if.
m+3/12=4m-5/7

Answer 1

m = 9/28

Explanation:

We are given that,

m + 3/12 = 4m - 5/7

solving for m,

`m + 3/12 = 4m - 5/7\\subtracting \ m \ on \ both \ sides,\\m-m+3/12 = 4m-m-5/7\\3/12=3m-5/7\\adding \ 5/7 \ on \ both \ sides,\\3/12 + 5/7 = 3m - 5/7 + 5/7\\27/28=3m\\dividing \ both \ sides \ by \ 3,\\27/(3)(28) = 3m/3\\9/28 = m\\`

Hence m = 9/28
