For this case we have the following system of equations:

We multiply the second equation by -5:

Now we add the equations:

We find the value of the variable "y":

THE solution is: (-6, -3)
Answer:
(-6, -3)
Answer for Problem 2:
x=61 degrees
Step-by-step explanation:
I'm not completely sure of problem 1, but I know what problem 2 is.
Tip: triangles always add up to 180 degrees.
1. 16+42= 58
2. 180-58= 122
3. 122 divided by 2= 61 degrees
ANSWER: x=61 degrees.
X=1.464102
Simplifies to: (1/2x)+1=1.732051
Step 1: Subtract 1 from both sides.
1/2x + 1 -1=1.732051-1
(1/2x)=0.732051
Step 2: Multiply both sides by 2
2*(1/2x) = (2) * (0.732051)
X=1.464102
I did this before and it’s the one on the left on the bottom
