$x = \frac{m}{2} - n$ $x = m/2 -n$

Write the equation as $2 (x + n) = m$ $2(x+n) = m$

You could multiply the 2 into the bracket, but in this case this is not a great idea because you will just to divide by 2 later.

Divide by 2 first to isolate the bracket which has the $x$ $x$

$\frac{2 (x + n)}{2} = \frac{m}{2}$ $(2(x+n))/2=m/2$

$x + n = \frac{m}{2}$ $x+n = m/2$

$x = \frac{m}{2} - n$ $x = m/2 -n$

How do you solve for x in m=2(x+n)m=2(x+n)?
