Answer:
x = -6
y = 8
Step-by-step explanation:
Using substitution method.
2x + y = -4 -----------(I)
y = - 4 - 2x -----------(II)
5x + 3y = -6 -------------------(III)
Substitute y = -4 -2x in equation (III)
5x + 3(-4-2x) = - 6
5x - 12 - 6x = -6
5x - 6x - 12 = -6
Combine like terms
-x - 12 = -6 {Add 12 to both sides}
-x = -6 + 12
-x = 6 {Multiply by (-1)}
x = -6
Substitute x = -6 in equation (II)
y = - 4 - 2*(-6)
= -4 + 12
y = 8

Answer:
Step-by-step explanation:
Number 2 first:
See the graph below for a hint. (Do you know how to use Desmos ?)
factoring seems to make no sense for 
but "guess and check" seems to work. I tried 4 for x, but that proved false. 3 for x made sense. You get 
so -9 +6 +4 = 1 is true. So (3,1)
x+y=4 becomes 3 + 1 = 4 Also true
According to the graph, (0,4) would also be a solution, so (3,1) and (0,4)
Part 1:
Factor 
as 
set each equal to 0 and get
x = -3 and x = -1 so the solutions seem be (-3,0) and (-1,0)
y = 2x + 6 factors to 2(x +3)
(-1,0) doesn't work!
But Desmos shows something else as a solution set for both:
(1,8)
y=2x+6 substitute values 8=2(1) +6 8=2+6 True
y = . Substitute values 
8= 1+4+3 True
