I believe its 6 Im actually so sorry if its wrong
Ответ:
to solve this, plug the values of the variables into each equation
(-1,5) x = -1 y = 5
x + y = 4
-1 + 5 = 4
4 = 4
the ordered pair is a solution to the first equation
x - y = -6
-1 - 5 = -6
-6 = -6
the ordered pair is a solution to the second equation
For an ordered pair to be a solution to a system, it must makes ALL the equations in the system true (which it did in this case); therefore, the ordered pair is a solution. Hope this helps!
