Step-by-step explanation:

Given

$mx + 2x = 6$

Required

Make the variable in bracket the subject

From the given expression, none of the variables (m and x) are in brackets.

So, I will solve for m and then solve for x

Solving for m:

$mx + 2x = 6$

Subtract 2x from both sides

$mx = 6 - 2x$

Divide both sides by x

$m = \frac{6 - 2x}{x}$

Solving for x:

$mx + 2x = 6$

Factorize

$x(m+2)= 6$

Divide both sides by m + 2

$x = \frac{6}{m+2}$
