Question

4x-20=mx-5m. find m​

Answer 1

`m=4`

Explanation:

So we have the equation:

`4x-20=mx-5m`

First, factor out a m from the right:

`4x-20=m(x-5)`

Divide both sides by x-5:

`m=(4x-20)/(x-5)`

Factor out a 4 in the numerator:

`m=(4(x-5))/(x-5)`

The (x-5)s cancel. Thus:

`m=4`

The value of m is 4 :)
