Answer:

[tex]m=4[/tex]

Step-by-step explanation:

So we have the equation:

[tex]4x-20=mx-5m[/tex]

First, factor out a m from the right:

[tex]4x-20=m(x-5)[/tex]

Divide both sides by x-5:

[tex]m=\frac{4x-20}{x-5}[/tex]

Factor out a 4 in the numerator:

[tex]m=\frac{4(x-5)}{x-5}[/tex]

The (x-5)s cancel. Thus:

[tex]m=4[/tex]

The value of m is 4 :)
