3. Solve for x.
When we transpose x terms to one side and number terms to
the other it would be best to put the x terms on the right, because
there are more x's on the right.
Divide both sides by 2
Notice what would happen if we transposed the terms to the
In this case, we have a negative coefficient on the unknown.
When you divide both sides of an inequality by a negative number,
you need to turn the inequality sign around.
We see that the rules about changing the direction of an
inequality if you multiply or divide by a negative but keep it
pointing in the same direction if you are multiplying or dividing by a
positive is necessary to keep our results consistent if you do the
