Step-by-step explanation:
Step1: Collect all the like terms
Like terms are similar variables, for example;
- (ax, 2ax) are all like terms since they have a common variable (ax)
- (by, -3by,by) are also like terms since they have a common variable (by)
- (c, c, -c) are also like terms since they have a common variable (c)
Step 2: Sum of all the groups of like terms
(ax+2ax)+(by-3by+by)+(c+c-c)=3ax-by+c
The answer is 3ax-by+c
