X=-6
You plus in x as -6 and you already know that y=5x and you plug in x=-6
It should look like 2(-6)-5(-6)=18
Since we are given with the three sides of the triangle and asked to determine the angle, we can use the cosine law.

45/n = 9/11 ;
11n = 9 * 45;
11n = 405;
11n / 11 = 405/11;
n = 36.8181818181818182 -----> answer choice: "B".

We can replace the inequality with qual sign:
2x - y = 4
x + y = -1
We can combine both question
3x = 3
x = 1
Since we know x = 1, we can solve for y by plug in in either equation:
x + y = -1
1 + y =-1
y = -2
or
2x - y = 4
2(1) - y = 4
-y = 2
y = -2
So the solution of this system of equation is the coordinate (1, -2)
