For this case we have the following system of equations:

[tex]x = 2-2y\\-1 = -2x-3y[/tex]

We substitute the first equation in the second equation:

[tex]-1 = -2 (2-2y) -3y\\-1 = -4 + 4y-3y\\-1 = -4 + y\\-1 + 4 = y\\y = 3[/tex]

Now, we look for the value of the variable "x":

[tex]x = 2-2 (3)\\x = 2-6\\x = -4[/tex]

Thus, the solution of the system is given by:

[tex](x, y): (- 4,3)[/tex]

Answer:

[tex](x, y): (- 4,3)[/tex]
