Pleas help Solve the following system of equations: x + 3y = −4
x + 5y = −6

(1, 1)
(−1, 1)
(1, −1)
(−1, −1)

The last option (-1,-1) is the right answer!
This is because when multiplying both expressions with y which is -1, it gives -3 and -5, and when you add -1 to both -3 and -5, you get -4 and -6 therefore satisfying the solution to the equation! Hope this helps!
