5w+vx=y make X the subject

Question

make X the subject 

Answer 1

So what you need to do is isolate x here.

5w + vx = y

 

Step one would be to subtract 5w:

5w + vx - 5w = y - 5w

vx = y - 5w

 

Step two now has us divide by v:

vx / v = (y - 5w) / v

x = ^{y - 5w}/_v

 

Get used to doing this process, a good portion of algebra is all about isolating variables to solve equations.
