Q4. Which of the following pairs of linear equations are consistent/inconsistent? If consistent, obtain the solution graphically:
Comparing these equations with , we get
As we can see
It means the given equations have exactly one solution and thus pair of linear equations is consistent.
Now The points(x, y) satisfying the equation are,
And The points(x,y) satisfying the equation are,
As we can see both lines intersects at point (2,2) and hence the solution of both equation is x = 2 and y = 2.
