Question 615185: Can someone please help me with these problems:Solve using the elimination method. If the system has no solution or an infinite number of solutions state this.
4x -5y = -31
-12 x +15y = 93

You can put this solution on YOUR website!
4x-5y = -31 Solve or y:
5y = 4x+31 Divide by 5.
y = 0.8x+6.2
-12x+15y = 93 Solve for y:
15y = 12x+93 Divide by 15.
y = 0.8x+6.2
As you can see, the equations are identical which means there is an infinite number of solutions.
