Explicație pas cu pas:
[tex] \frac{(3x - 5)}{4} - \frac{(x - 7)}{6} = \frac{(x - 5)}{3} + 1 \\ \\ 12 \times ( \frac{(3x - 5)}{4} - \frac{(x - 7)}{6} ) = 12 \times ( \frac{(x - 5)}{3} + 1 \\ \\ 3(3x - 5) - 2( x - 7) = 4(x - 5) + 12 \\ 9x - 15 - 2x + 14 = 4x - 20 + 12 \\ 7x - 1 = 4x - 8 \\ 7x - 4x = - 8 + 1 \\ 3x = - 7 \\ x = - \frac{7}{3} [/tex]
