Question

4x+6y=3
-10x-15y=-4
No solution right?

Answer 1

I can't find a solution. So I'd say yeah, there's no solution.

Answer 2

do linear algbra way made into a matrix then u do rref to it
the matrix will be 1 15 0
0 0 1
As see the second row is 0 0 1 which tell you the system is inconsistance hence no solution

Answer 3

Yes, Indeed there is no solution. You get a solution of equations when they intersect each other at a particular point in any quadrant. If you have a graphical view of these equations, then they will not intersect each other; which indeed means "NO SOLUTION AT ALL" (hope this works)
