1) 2n+5n–n+6n=
2)x+x elebado a 2 –2x+3x elebado a 2 =
3)x+5+2x–2=
4)2x+2y+x–3y=
5)x–4x+3x+2x=
6)5x/4 – x/2 + y – y/3=

Answer 1

2n+5n-n+6n = 12n

x + x² - 2x + 3x² = -x + 4x²

x + 5 +2x - 2 = 3x + 3

2x + 2y + x - 3y = 3x - y

x - 4x + 3x + 2x = 2x

5x/4 - x/2 + y - y/3=
(5-2)x/4  + (3-1)y/3
3x/4 + 2y/3
