Question

Is (3,6) a solution of the system of linear equations below? Justify your response. Use of the graph is optional.

-6x + y= -12

X + y= -3

Answer 1

No.

Explanation:

The given system of equations are :

-6x + y= -12 ......(1)

x + y= -3 ......(2)

Put x = 3 and y = 6 in both equations i.e.

-6(3) + (6) = -12

And

3 + 6 = 9 ≠ -3

Hence, (3,6) is not the solution of the given system of equations.
