Explanation:
x - y = 16 ---eq(1)
x - y = 16 ---eq(2)
From eq(1)
x - y = 16
x = 16 + y ---eq(3)
Substituting the value of eq(3) into eq(2)
(16 + y) - y = 16
16 = 16
We can't get a proper value for this pair of linear Equations
But, Since both the equations are the same, the lines formed by them will be coincident and therefore they will have infinitely many solutions
