Answer 1

Explicación paso a paso:

[tex] \frac{3x - 1}{2} + 5 = 2x + 3 \\ \frac{3x - 1}{2} + \frac{10}{2} = 2x + 3 \\ \frac{3x - 1 + 10}{2} = 2x + 3 \\ \frac{3x + 9}{2} = 2x + 3 \\ 3x + 9 = 4x + 6 \\ 3x - 4x = 6 - 9 \\ - x = - 3 \\ x = 3[/tex]

[tex]3x - 2 = x - 4 \\ 3x - x = - 4 + 2 \\ 2x = - 2 \\ x = \frac{ - 2}{2} = - 1[/tex]

[tex]2(x - 3) + 1 = 3 \\ 2x - 6 + 1 = 3 \\ 2x - 5 = 3 \\ 2x = 3 + 5 \\ 2x = 8 \\ x = \frac{8}{2} = 4[/tex]

[tex]3x = 6 - (x + 2) = \\ 3x + x = 6 - 2 \\ 4x = 4 \\ x = \frac{4}{4} = 1[/tex]

[tex]3x - 7 = 4x + 1 \\ 3x - 4x = 1 + 7 \\ - x = 8 \\ x = - 8[/tex]

espero te sirva
