Add like terms
3y + 2y = 5y
4x - x = 3x
Answer: 3x + 5y
Hope this helped! ;P
4x + 3y - x + 2y
= 4x - x + 3y + 2y
= 3x + 5y
4x - x + 2y +3y
as you see we can factorize --
= x(4-1) + y(2+3)
= x(3) + y(5)
= 3x + 5
its not necessary to factorize but for a person who is new, it helps him understand better
4x+3y-x+2y
If it makes it easy for you, group the x's and y's together.
(4x - x) + (3y + 2y)
Then add them together.
3x + 5y
ok
u simply count the like terms, the xes togther and the ys together:
4x-x+3y+2y
3x+5y :D there u go
