Question

4x-20=mx-5m. find m​

Answer 1

Answer:

$m=4$

Step-by-step 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:

$m=\frac{4x-20}{x-5}$

Factor out a 4 in the numerator:

$m=\frac{4(x-5)}{x-5}$

The (x-5)s cancel. Thus:

$m=4$

The value of m is 4 :)
