Multiply the first equation by -3. Add the two equations. $2x-\ 5y=17\ \ \ \$ multiply by -3$\ \ \ \ -6x+15y=-51$ $6x-15y=51\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 6x-\ \ 5y=\ \ \ 51$ $\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 0=\ \ \ \ \approx0$
