Question

simplifique as expressões ​

Answer 1

Resposta:

a) 8z + 3

$17z + 3 - 9z = \\ 17z - 9z + 3 = \\ 8z + 3$

b) 5x + 4

$5(x + 4) - 16 = \\ 5x + 20 - 16 = \\ 5x + 4$

c) 15a - 2

$9a + 5 - 7 + 6a = \\ 9a + 6a + 5 - 7 = \\ 15a - 2$

d) - 12b - 15

$5(5b - 3) - 37b = \\ 25b - 15 - 37b = \\ 25b - 37b - 15 = \\ - 12b - 15$
