Question

Solve for x: m(fx+a)=z+g

Answer 1

First you need to divide m over to get fx+a=(z+g)/m
Then you subtract a on both sides to get fx=((z+g)/m)-a
Next you divide f on both sides to get x=((f(z+g)/m)-(a/f) which is your awnser.

Answer 2

X= -a/f = z/mf + g/mf
-a is over f
+ z over mf
+ g over mf
