comment Multivariable Chain Rule
I Took the derivative of both sides, and obtained the following: $G'(x^2+y^2,x+y)\cdot\begin{bmatrix} 2x&2y \\ 1&1 \end{bmatrix}=\begin{bmatrix} 7&3 \\ 1&5 \end{bmatrix}$ @EricTowers, but i have no idea how i should do next

comment Where $a$ and $b$ are both constants, find the values of $a$ and $b$
great!! but just for curiosity, what if instead of using using -1/3 for the value of x, you use a different number such as 3? would it still be possible to find that a=2 and that b=3?

well maybe there is, I checked and double checked my textbook and many friends are also having problems with this particular exercise, maybe there is a mistake in the textbook. Thanks!
