$\begin{cases} { x }^{ 2 }+{ y }^{ 2 }=30 \\ x+y=10 \end{cases}$

If the above equations are true simultaneously, then find the value of $xy$.

$\large \begin{cases} { a(b+c)=32 } \\ { b(c+a) = 65 } \\ {c(a+b) = 77 } \end{cases}$

Given that $a , b,$ and $c$ are positive real numbers that satisfy the system of equations above, find the value of $abc$.

$x+y$

You think you rock at linear equation? Gimme the solution NOT using hit and trial method! Solve for the values of "x" and "y" and enterNote: These are not linear equations.
