you draw as accurately as possible on graph paper the line
y = 2x - 4 and y = 2x - 6 and find the point where they meet.
However in this case, the two lines are parallel, so there is no solution to this problem

These equations are not possible cause amount of 2x-y in first equation is same as second equation .So,other side of bout equation must be equal but as you see 4 is not equal by 6.

Take different values for x and work out the values for y for each equation. If both equations are plotted, and if they intersect, the point of intersection will have x and y values that are satisfied by both the equations.
2x - y = 4
2x - y = 6
In the present case, I don't see them intersecting. They are parallel to each other.
The value of y when x = 0 and the value of x for which y = 0 can be treated as solutions for that equation.
