equations

To solve for X in the equation you see here: TO GET X BY ITSELF OUR FIRST STEP: To isolate the term containing X, which In this case is 2X. To isolate 2X, we have to get rid of this +3 by subtracting three from both sides of the equation. ON THE LEFT: +3-3 cancels, and we are left with 2X. ON THE RIGHT: 5-3 simplifies to two. TO GET X BY ITSELF, since it´s been multiplied by two; we just divide both sides of the equation by two. ON THE LEFT: the two´s cancelled ON THE RIGHT: two over two simplifies to one. SO OUR ANSWER IS X=1 And feel free to check your answer by plugging a one back in for X in the original equation.
