Question

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

Answer 1

See a solution process below:

Explanation:

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)`
