Question

If 9x + 2a = 3a-4x, then what does x equal?

Answer 1

`x = a/13`

Explanation:

To solve this problem you must perform the necessary math to isolate the `x` terms on one side of the equation and the `a` terms on the other side of the equation while keeping the equation balanced:

`9x + 2a - 2a + 4x = 3a - 4x - 2a + 4x`

`9x + 4x + 2a - 2a = 3a - 2a - 4x + 4x`

`13x + 0 = 1a + 0`

`13x = a`

`(13x)/13 = a/13`

`(cancel(13)x)/cancel(13) = a/13`

`x = a/13`
