Question

Determine o valor numérico que torna a equação a seguir, verdadeira:

Answer 1

(2x - 1)/4 + (3x + 1)/6 = (5x - 3)/8
6(2x-1)/24 + 4(3x + 1)/24 = (5x -3)/8
(12x -6)/24 + (12x + 4)/24 = (5x-3)/8
(24x -2)/24 = (5x - 3)/8
8(24x -2)  = 24 ( 5x - 3)
24x - 2 = 3(5x - 3)
24x  - 2 = 15x -9
24x -15x = -9 + 2
9x = -7
x = -7/9
