Question

$\frac{2x - 1}{4} - \frac{x - 1}{3} = \frac{x + 1}{2} + \frac{3x + 1}{5}$

Answer 1

2x-1/4 - x-1/3 = x+1/2 + 3x+1/5

6x-3-4x-4/12=5x+5+6x+2/10

simplifica o 12 e o 10

6x-3-4x-4/6=5x+5+6x+2/5

multiplica cruzado

30x-15-20x-20=30x+30+36x+12

deixa tds as incógnitas do msm lado

30x-20x-30x-36x=30+12+15+20

-56x=77  x=-77/56
