Multiply the first equation by 3 and the second equation by 2:

$\begin{cases}6x-9y=27\\6x+10y=8\end{cases}$

Subtract the two equation to get rid of the x variable:

$-9y-10y=27-8 \iff -19y = 19 \iff y = -1$

Use the value of y to determine the value of x: for example, using the first equation we have

$2x+3=9 \iff 2x=6 \iff x=3$
