a) 9x + 15 - 8x - 10 =

c) 9s² - 4s + 11s - 2s² =

b) 8x - 2y + 4x + 2y =

d) -9x - x + a + b + 2a - 2b + 5x=​

Answer 1

Resposta:

a) 9x + 15 - 8x - 10 =

9x-8x+15-10=

x+5

c) 9s² - 4s + 11s - 2s² =

9s²-2s²-4s+11s=

7s²+7s

b) 8x - 2y + 4x + 2y =

8x+4x-2y+2y=

12x

d) -9x - x + a + b + 2a - 2b + 5x=

-9x+5x-x+a+2a+b-2b

-5x+3a-b
