Question

resolva a equeçao 2(3x=1)+5x=0

Answer 1

2(3x + 1 ) + 5x = 0

6x + 2 + 5x = 0

6x + 5x = - 2 

11x = - 2 

x = - 2/11

Answer 2

Vc multipliva 2.(3x+ ou - 1) + 5x= 0
6x +\- 2 + 5x = 0
Ai vc passa o +\- 2 pro outro lado com o sinal contrario
6x + 5x = +/- 2
11x = +/- 2
Ai vc passa o 11 dividindo
X = +-2/11
