Alvin’s first step in solving the given system of equations is to multiply the first equation by 2 and the second equation by –3. Which linear combination of Alvin’s system of equations reveals the number of solutions to the system? 9x + 4y = 36 6x + 2.5y = 24 Infinite solutions: 0x – 0y = 0 No solutions: 0x + 15.5y = 144 One solution: 0x + 0.5y = 0 Two solutions: 0x – 0.5y = 60
