2) 2y – y – 10y =
3) 4a + a – 7a =
4) x²+ x² - 2x² =
5) ab – ab + 5ab =
6) 4x³- x³ + 2x³ =
7) 10x – 13x –x =
8) 8x – 10x + 4x =
9) 6x + (2x – 4) – 2 =
10) 7y -8 – (5y – 3) =​

Answer 1

Explicação passo-a-passo:

1) 10x - 5x = 5x

2)2y - 11y = -9y

3) 5a - 7a= - 2a

4) 2x² - 2x²= 0

5) ab - ab +5ab= +5ab

6) 3x³ +2x³=5x³

7) 10x - 14x = - 4x

8) 12x - 10x = 2x

9) 6x +2x -4 -2= 8x - 6

10) 7y - 8 - 5y +3= 2y - 5

Answer 2

Reduza os termos semelhantes nas seguintes expressões algébricas:

1) 7x -5x + 3x
= 2x + 3x
= 5x
_________

2) 2y – y – 10y
= y - 10y
= - 9y
_________

3) 4a + a – 7a
= 5a - 7a
= - 2a
________

4) x²+ x² - 2x²
= 2x^2 - 2x^2
= 0

______________

5) ab – ab + 5ab
= 5ab
_______

6) 4x³- x³ + 2x³
= 3x^3 + 2x^3
= 5x^3
_____________

7) 10x – 13x –x
= 10x - 14x
= - 4x
______________

8) 8x – 10x + 4x
= 12x - 10x
= 2x
__________

9) 6x + (2x – 4) – 2
= 6x + 2x - 4 - 2
= 8x - 6
_________

10) 7y - 8 – (5y – 3)
=​ 7y - 8 - 5y + 3
= 2y - 5
