Explicación paso a paso:
[tex]5x + 1 = 3x - 4 \\ 5x - 3x = - 4 - 1 \\ 2x = - 5 \\ x = \frac{ - 5}{2} \\ 5 \times \frac{ - 5}{2} + 1 = 3 \times \frac{ - 5}{2} - 4 \\ \frac{ - 25}{2} + 1 = \frac{ - 15}{2} - 4 \\ \frac{ - 25}{2} + \frac{2}{2} = \frac{ - 15}{2} - \frac{8}{2} \\ \frac{ - 23}{2} = \frac{ - 23}{2} [/tex]
espero te sirva
