Explicación paso a paso:
[tex]6y - 3(1 - y) = 8(y - 6) \\ 6y - 3( - y + 1) = 8(y - 6) \\ 6y + 3y - 3 = 8y - 48 \\ 9y - 3 = 8y - 48 \\ 9y - 8y = - 48 + 3 \\ y = - 45[/tex]
[tex] \frac{x + 21}{3} = x - 9 \\ x + 21 = 3x - 27 \\ - 3x + x = - 27 - 21 \\ - 2x = - 48 \\ 2x = 48 \\ x = \frac{48}{2} = 24[/tex]
[tex]x - y = 24 - ( - 45) = 69[/tex]
espero te sirva
