Take two integers \(x\) & \(y\)
\(x + y = 43\) & \(x^2 - y^2 = 43\)
\((x+y)(x-y) = 43\) :: \(x - y = 1\)
By solving two bold equations, we will get \(x = 22\) & \(y = 21\)
Answer D
\(x + y = 43\) & \(x^2 - y^2 = 43\)
\((x+y)(x-y) = 43\) :: \(x - y = 1\)
By solving two bold equations, we will get \(x = 22\) & \(y = 21\)
