Question

Reduza os termos semelhantes:
a) 7 x – 5 x + 3 x = d)2 y – y – 10 y =

b)10 x – 13 x – x = e)8 x – 10 x + 4 x =

c) 4 a + a – 7 a =
​

Answer 1

Resposta:

a)  7x -5x + 3x = (R: 5x)

b)  10x – 13x –x = (R: -4x)

c)   4a + a – 7a = (R: -2a)

d)   2y – y – 10y = (R: -9y)

e)  8x – 10x + 4x = (R: 2x)
