Solve 3x - 5y = 17 and 9x - 15y = -4

Solution:

The given equations are linear equations which can be solved simultaneously as shown below:

3x - 5y = 17 ---(1)

9x - 15y = -4 ----(2)

Multiply (1) by 3 and subtract (2) from it

9x - 15y = 51
9x - 15y = -4
0x - 0y = 55

Since the left hand side is zero implies that the set of equations are inconsistent and hence No solution.

Solve 3x - 5y = 17 and 9x - 15y = -4

Summary:

On solving 3x - 5y = 17 and 9x - 15y = -4 there is no solution as the set of linear equations are inconsistent.
