You can put this solution on YOUR website! Solve the following system of equations and state answer in coordinate pairs?x=2y and x^(2)+y^(2)=(5)/(16)
----
substitute for "x and solve for "y":
(2y)^2 + y^2 = (5/16)
---
5y^2 = 5/16
----
y^2 = 1/16
y = +(1/4) or y = -1/4
------
Solve for "x":
x = 2y
If y = 1/4, x = 1/2; If y = -1/4, x = -1/2
