... and dividing both sides by 3), we find out that when x=1, the equation is true. We can solve ANY linear equation in this way. In a quadratic equation, it’s not as easy—unless we can factor the equation. For example, if we know that 2x2 + 7x + 6 = 0, and then we find that we can factor the equation i ...

... adding, and substitution. The natural question is, Which method should I use in a given situation? Graphing is the least exact of the methods, and solutions may have to be estimated. The algebraic methods—addition and substitution—give exact solutions, and both will work for any system of linear equ ...
