... If the same amount is added or subtracted from both expressions in an equation, the result is another, equivalent equation (with the same solution). Rule: A number that is added /subtracted in one expression can be eliminated from that expression if it is subtracted /added from the other expression. ...

Math 90, Factoring Handout
... Our goal is to eliminate one of the variables. To do this, we either add (when variables are opposite signs) or subtract (when variables are the same sign.) Sometimes we need to multiply one or both of the equations to get the coefficients (the number in front of the variable) to be the same so that ...
