See a solution process below:

Divide each side of the equation by $color(red)(a + b)$ to solve for $x$ while keeping the equation balanced:

$((a + b)x)/color(red)(a + b) = c/color(red)(a + b)$

$(color(red)(cancel(color(black)((a + b))))x)/cancel(color(red)(a + b)) = c/(a + b)$

$x = c/(a + b)$

How do you solve for x in (a+b)x=c (a+b)x=c ?
