Question

Is. x=-1and y=3 a solution of the system. 7y+2y=-1.,5x-3y=-14​

Answer 1

Answer:

No

Step-by-step explanation:

7y+2y=-1

7×3 + 2×3 = 21 + 6 = 27 ≠ 1

for this equation y ≠ 3.

5x-3y=-14

5×-1 - 3×3 = -15 - 9 = -26 ≠ -14

for this equation x ≠ -1 and y ≠ 3

=> x=-1and y=3 is not a solution of the system .
