Solve using the elimination method. Show your work. If the system has no solution or an infinite number of solutions, state this.
10x + 5y = 52.5
30x – 7y = 80.5

Multiply the first equation by 3, then subtract the second from it. Solve for y. Then insert the y value into one of the equations to find x. Then make your statement.
