Question

3 ( x+2) /5 - 3×+1 /4 =2

Answer 1

▪Aplicando chuveirinho:
(3x+6)/5 - 3x+1/4 = 2

▪Tirando minimo:
(12x+24 - 15x-5)/20 = 2
-3x+19=40
-3x = 21
x = -7

Answer 2

Vamos lá:

3(x+2)/5 - (3x+1)/4 = 2
mmc de 5 e 4 = 20

12(x+2) - (15x+15) = 40
12x + 24 - 15x - 15 = 40
-3x = 40 - 9
-3x = 21
x = 21/-3
x = -7
