6 xy² - 8 xy²=
7x - 5x + 3x=
4a +a - 7a =
8x - 10x + 4x =
ab - ab + 5ab =
8x + 12x =
3a - 23a =
12x + 13x =

Answer 1

Resposta:

1) 10a

2) 7y²

3) - 2xy²

4) 5x

5) - 2a

6) 2x

7) 5ab

8) 20x

9) - 20a

10) - 25x

Explicação passo-a-passo:

1)

$8a + 2a = 10a$

2)

$2 {y}^{2} - 9 {y}^{2} = 7 {y}^{2}$

3)

$6x {y}^{2} - 8x {y}^{2} = - 2x {y}^{2}$

4)

$7x - 5x + 3x = 5x$

5)

$4a + a - 7a = - 2a$

6)

$8x - 10x + 4x = 2x$

7)

$ab - ab + 5ab = 5ab$

8)

$8x + 12x = 20x$

9)

$3a - 23a = - 20a$

10)

$12x + 13x = 25x$
