1. w+(w-3)+(w+2)= 38
Solve this equation to get the number of white ribbons then plug in that number to solve for the rest of the ribbons

2. first you add one to both sides
3w-1=38
+1 +1

then you divide both sides by 3
3w=39
/3 /3

w=13

go back and plug in 13 in every w.Remember to follow the order of operations

13+(13-3)+(13+2)=38
13+(10)+(15)=38
38+38

:D
