You can type those equations into the desmos graphing calculator online! find the feasible region (where all the colors overlap) and find the vertices then fill them into the objective function! if you have any more questions then let me know!!
Answer:
3
Step-by-step explanation:
set the two equations equal to each other
2y+3 = 5y-6
