Explicación paso a paso:
[tex]2x + 3 = x + 4 \\ 2x - x = 4 - 3 \\ x = 1 \\ 2 \times 1 + 3 = 1 + 4 \\ 2 + 3 = 5 \\ 5 = 5[/tex]
[tex]6x + 30 - 5x = 25 \\ x + 30 = 25 \\ x = 25 - 30 \\ x = - 5[/tex]
[tex]2x - 1 = 5x + 8 \\ 2x - 5x = 8 + 1 \\ - 3x = 9 \\ 3x = - 9 \\ x = \frac{ - 9}{3} = - 3[/tex]
[tex]4x - 10 = 2x + 2 \\ 4x - 2x = 2 + 10 \\ 2x = 12 \\ x = \frac{12}{2} = 6[/tex]
espero te sirva
