The "solution" to a system of equations basically means an ordered pair that makes both equations true when you put it into the equation. In other words, a value that works! So let's try it.
A is (2, -3). x is 2, y is -3. x+y=-1. 2+(-3)=-1. 2-3=-1. -1=-1. This works! But it needs to work in BOTH equations, so let's try that. x-3y=11. 2-3(-3)=11. 2+(-3*-3)=11. 2+9=11. 11=11! This is TRUE, so A is correct!!
Answer: A (2, -3)
Part A: B)35
As the angle y° equals to angle 2x°, y=2x.
And the sum of the angle (x+y+5°)and the angle 2x° is 180°.Therefore,
x+y+5°+2x =180°
x+2x+5°+2x=180°
5x+5° =180°
5x =175°
x =35°
Part B: C)110°
As I said, y =2x
And the unlabled angle eaquals to the angle(x+y+5°).
Therefore,
the unabled angle= x+y+5°
=x+2x+5°
=3x+5°
=3(35°)+5°
=110°
