Question

How many solutions does y=5x+12 and y=5x+18

Answer 1

No solutions

There is no possible way with the same variables can you find a solution to this problem

Answer 2

there is no solution for these linear equations in two variables.

since a1 (y) = a2 (y)

b1 (5x) = b2 (5x)

but, c1 (12) not equal to c2 (18)
