Graph of Parallel lines shows a system of equations with no solutions
Step-by-step explanation:
Consider a set of equations

If we solve this both equations using any one of the solving method, (Substitution method) then we will get

substituting the following x in 2nd equation (21x + 6y = 24) We get

Put y= -2 in x equation

Comparing these (x,y) values we can understand that they never meet at a point
X= pi/4 +k(pi)
