Calcule as operações abaixo A)20x +6b +2x-5b+x +11 B)2b +18 +5b -12s +7x +3b C)11a +2x -3a +8x -6c+2a

Answer 1

Resposta:

A) 20x + 6b + 2x - 5b + x + 11 =

20x + 2x + x + 6b - 5b + 11 =

23x + b + 11

B) 2b + 18 + 5b - 12s + 7x + 3b =

2b + 5b + 3b + 18 - 12s + 7x =

10b + 18 - 12s + 7x

C) 11a + 2x - 3a + 8x - 6c + 2a =

11a - 3a + 2a + 2x + 8x - 6c =

10a + 10x - 6c
