Question

solve 6x-10y=12; -15x+25y=-30.

Answer 1

lets see if we can't make this easier....lets reduce the equations
6x - 10y = 12 becomes 3x - 5y = 6
-15x + 25y = -30 becomes -3x + 5y = -6

now if you were to add these...
3x - 5y = 6
-3x + 5y = -6
--------------add
0 + 0 = 0

There is an INFINITE MANY SOLUTIONS for this set of equations
