Answer:

No, (4, -3) is not a solution to the system of equations

Step-by-step explanation:

If (4, -3) is a solution to the given system of equations, then

for x = 4, and y = -3, both of the equations are satisfied.

x - y = 4 - (-3)

= 4 + 3

= 7

This is not 4, so the first equation is not satisfied

2x + y = 2(4) + (-3)

= 8 - 3

= 5

This equation is satisfied

It is sufficient to conclude that (4, -3) is not a solution to the system of equations since it doesn't satisfy the first equation
