Answer:
(2, –3) is a solution to the system of linear equations.
Step-by-step explanation:
3x - y = 9
4 x + y = 5.
Add the equations
7x = 14
x = 2
Substitute it back into either original equation to find x
3(2) - y = 9
6 - y = 9
y = -3
4(2) + y = 5.
8 + y = 5
y = -3
x = 2
y = -3
(2, -3)
(2, –3) is a solution to the system of linear equations.
