put this solution on YOUR website!You need to get like terms on the same side of the equation; i.e., get the 'x' terms all on one side and the scalars on the opposite side. So, let's start by adding 1 to both sides of the equation:
. That equates to:
. Next, let's add 4x to both sides thusly:
, which simplifies to: 12x = 24. To solve for x, we have to divide both sides by 12:
, and that simplifies to
. To check our work, we substitute 2 into the original equation. This produces:
, which equates to
, which simplifies to 15=15. Because 15=15 is a true statement, that proves our answer of
is correct.
