# Systems of Equations

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

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 \(abc\).

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 enter \(x+y\)

Note: These are not linear equations.
