... Consequently, x = 1 and substituting into either Equation 1 or 4 produces y = −1. The point (1, −1) is the intersection of the two lines described by the two equations and is the only point that satisfies both. There is an important point here. We have replaced the equation 3x + 2y = 1 with the equat ...
