Explicación paso a paso:
Primera ecuación:
[tex]4x + 8 = 2x - 6 \\ 4x - 2x = - 6 - 8 \\ 2x = - 14 \\ x = - 7[/tex]
Comprobando
[tex]4x + 8 = 2x - 6 \\ 4( - 7) + 8 = 2( - 7) - 6 \\ - 28 + 8 = - 14 - 6 \\ - 20 = - 20[/tex]
Segunda ecuación
[tex]5x - 24 = 56 \\ 5x = 56 + 24 \\ 5x = 80 \\ x = 16[/tex]
[tex]5x - 24 = 56 \\ 5(16) - 24 = 56 \\ 80 - 24 = 56 \\ 56 = 56[/tex]
Tercera ecuación
[tex]6x + 16 = 152 \\ 6x = 152 - 16 \\ 6x = 136 \\ x = 22.67[/tex]
[tex]6x + 16 = 152 \\ 6(22.67) + 16 = 152 \\ 136 + 16 = 152 \\ 152 = 152[/tex]
