To solve such systems, we can use several methods: substitution, elimination, or graphing. In this case, we opted for the elimination method. We manipulated the equations to eliminate one variable and solve for the other. After solving for ( x ), we substituted that value back into one of the original equations to find ( y ). The final solution shows that the system has one unique solution, which means the lines represented by the two equations intersect at a single point on the coordinate plane.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>How many solutions does this system have?
