X + 3y = −4 x + 5y = −6
lesya [120]

For this case we must solve the following system of equations:

x + 3y = -4\\x + 5y = -6

We clear x of both equations:

x = -4-3y\\x = -6-5y

We match:

-4-3y = -6-5y\\-3y + 5y = -6 + 4\\2y = -2\\y = \frac {-2} {2}\\y = -1

We find the value of "x":

x = -4-3 (-1)\\x = -4 + 3\\x = -1

Thus, the solution of the system is:

(x, y): (- 1, -1)

Answer:

(x, y): (- 1, -1)
