Given that the value of b can never equal to -1 determine if the equation are intersecting , parallel , or coincident
X+y= ab
Bx-y= a

The equations are intersecting lines

Step-by-step explanation:

The given equations are:

Add both equations:

Factor

Since b≠-1, we can 1+b is different from zero.

This means that:

From equation 1,

The two equations intersect at:

(a,ab-a)
