Thread: Find the value of x and y satisfying the given equation:

x^2 + y^2 = 4 and x/2 + y =1

Hi
Substitute x = 2-2y into equation x²+y²=4
You will find a quadratic
Solve for y

u know i already did that...
& on solving for y, i got 2 values of y= 0 & 8/5
can u tell me which value of y do i consider for finding out x??

Both of them. This problem has two solutions.
