Resolva isso aqui se és capaz.
2x—1
——— = 7
3x+6

Answer 1

$\frac{2x - 1}{3 x + 6} = 7 \\ 2x - 1 = 7(3x + 6) \\ 2x - 1 = 21x + 42 \\ 19x = - 43 \\ x = \frac{ - 43}{19}$

Answer 2

$\frac{2x-1}{3x+6} = 7\\ \\ 2x-1= (3x+6).7\\ \\ 2x-1=21x+42\\ \\ 21x-2x= -1-42\\ \\ 19x = -43\\ \\ x= -43/19$

Resposta → -43/19
