[tex]15х – 8(3х – 4) = 14 \\ 15x - 24x + 32 - 14 = 0 \\ - 9x + 18 = 0 \\ - 9x = - 18 \\ 9x = 18 \\ x = 2[/tex]
[tex] \frac{3x - 4}{7} - \frac{2x}{3} = \frac{x + 4}{2} \\ 6(3x - 4) - 14 \times 2x = 21(x + 4) \\ 18x - 24 - 28x - 21x - 84 = 0 \\ - 31x - 108 = 0 \\ - 31x = 108 \\ x = - \frac{108}{31} [/tex]
