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.
