Notice that both of these equations are shown on the graph in Figure 1. The lines intersect at zero points. If a 0 there are two casesEither b equals also 0 and every number is a solution.
B 1 Play With It.
The slopes and the y-intercepts of the lines will determine the kind of solution the system will have. Equation with two variables. Note that most linear equations will not start off in this form. As a result of applying a system of equations to a real-world situation we know that there were 172 adults and 86 children at the party.
