Incorrect. Solve each system of equations by eliminating variables through multiplication and addition. If after adding you get the statement $\displaystyle{0}={0}\usepackage{cmbright}\Huge\$ for two sets of equations in the system, there are an infinite number of solutions. If you get a false statement that sets 0 equal to any other number, there are no solutions to the system. If you find a value for each variable, there is one solution to the system.
