Question

2. Tell whether the ordered pair (-1,-2) is the solution of the system. x + y =

-3 and 2x - y = -4*

Answer 1

Not the solution tp the system because the ordered pair should be true for both equations. However the last equation is not true.

Explanation:

(-1,-2) is the solution of the system. x + y =-3 and 2x - y = -4*

x + y =-3 :

(-1)+ (-2) = -3

-1-2 =-2 -3=-3

2x - y = -4:

2(-1)-(-2)=-4

(-2) -(-2)= -4

0=-4
