- 10x + 8y = - 6- - - - - Equation 1
y = (5/4)x- - - - - - - -- Equation 2
- - - - - - - - - - - - -
Insert the y value of equation 2 into equation 2
- 10x + 8y = - 6
- 10x + 8(5/4)x = - 6
- 10x + 40/4x = - 6
- 10x + 10x = - 6
The coefficients and variable cancell.
No solution

8Y = (5/4)*8X = 10X
SO, -10X +8Y = 10X + 10X =0
SO YOUR PROBLEM IS INCORRECT
