3x-y=4
2x+y=6
Add the two equations together:
5x=10
x=2
Plug 2 for x into the second equation:
2(2)+y=6
4+y=6
y=2
The solution is (2,2)

Answer:
use parentheses to show multiplication rather than an x because it is detected as a letter x instead of a times symbol

Answer:
KPF = 9 and H = 129
Step-by-step explanation:
An inscribed quadrilateral in a circle has all diagonal angles add up to 180, so we can use this to find the angles of the quadrilateral.
H= 180-EPK and K = 180-E so H = 129 and K = 60
Now PF and EH are parallel, so PE is a transversal. That means FPE = 180 - E = 60. Now it's pretty easy to solve for KPF = FPE - EPK = 60 - 51 = 9.
Let me know if you don't see how I did any of this and I'll be happy to explain it..
