The perimeter of a triangle is 26 c,. Side a of the triangle is 3 cm longer than side b. Side c is 1 cm shorter than twice side b. Find the length of each side.

math 
bobpursley,
a+b+c=26
a=b+3
c=2b1
can you take if from here? 
math 
Reiny,
a = b+3
c = 2b  1
a + b + c = 26
b+3 + b + 2b1 = 26
b = 8
a = 11
b = 8
c = 15
