Step-by-step explanation:
substitute the values
px=3x+1
=(3x+1)/x
=3x/x +1/x
=3+1/x
rx=2x²+5
p(r(x)) =(3+1/x(2x²+5))
=6x²+15+2x²/x+5/x
=3(2x²+5)+1/x(2x²+5)
=(2x²+5)(3+1/x)

All you have to do is add those two numbers given and subtract by 180. all of the angles shall add up to 180 if not then you dic something wrong
Solve the system using substitutions:
x has a value of 1. Use this value to find the value of y.
y has a value of 1.
x=1
y=1
