Question

4(2x + 4) = 10x + 13 - 2x + 3.
Solve for x

Answer 1

x is any Real number

Explanation:

We first apply distributive property on the left to get rid of the grouping symbol, and then combining the like terms (linear terms on one side and numerical terms on the other side of the equation):

`8x+16=10x+13-2x+3\\16-13-3=10x-2x-8x\\0=0`

This equation results on a TRUE equality Zero = Zero, which means that any value we use for "x" in the original expression will always render an equality.

Therefore x is any Real number.
