Step-by-step explanation:
Given
![mx + 2x = 6](https://tex.z-dn.net/?f=mx%20%2B%202x%20%3D%206)
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](https://tex.z-dn.net/?f=mx%20%2B%202x%20%3D%206)
Subtract 2x from both sides
![mx = 6 - 2x](https://tex.z-dn.net/?f=mx%20%3D%206%20-%202x)
Divide both sides by x
![m = \frac{6 - 2x}{x}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B6%20-%202x%7D%7Bx%7D)
Solving for x:
![mx + 2x = 6](https://tex.z-dn.net/?f=mx%20%2B%202x%20%3D%206)
Factorize
![x(m+2)= 6](https://tex.z-dn.net/?f=x%28m%2B2%29%3D%206)
Divide both sides by m + 2
![x = \frac{6}{m+2}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B6%7D%7Bm%2B2%7D)
