Please help me how you get the answer. PLEASE I NEED HELP. A triangle sail has a perimeter of 25 m. Side a is 2 m shorter than twice side b, and side c is 3 m longer than side b. Find the length of each side. Thank you ver much for helping me

a+b+c=25
a=2b2
c=b+3
a+b+c=25
(2b3)+b+(b+3)=25 solve for b, then solve for a, and c
