Question

Resolva a expressão dada:

5x + 3 - {2x + [3(3-2x)-2(1-x)]+3}​

Answer 1

Resposta:

2x + 3 (3 - 2x) - 2 (1 - x) = 0

2x + 3 (3 - 2x) - 2 (1 - x) = 02x + 9 - 6x - 2 + 2x = 0

2x + 3 (3 - 2x) - 2 (1 - x) = 02x + 9 - 6x - 2 + 2x = 02x - 6x + 2x = 0 - 9 + 2

2x + 3 (3 - 2x) - 2 (1 - x) = 02x + 9 - 6x - 2 + 2x = 02x - 6x + 2x = 0 - 9 + 2- 2x = - 7

2x + 3 (3 - 2x) - 2 (1 - x) = 02x + 9 - 6x - 2 + 2x = 02x - 6x + 2x = 0 - 9 + 2- 2x = - 7x = - 7/- 2

2x + 3 (3 - 2x) - 2 (1 - x) = 02x + 9 - 6x - 2 + 2x = 02x - 6x + 2x = 0 - 9 + 2- 2x = - 7x = - 7/- 2x = 7/2 ou 3,5
