Procedimiento7x - 2(x + 1) - 8 = 4x - (3 - x) - 7?
Procedimiento 7x - 2(x + 1) - 8 = 4x - (3 - x) - 7 ?
Procedimiento 7x - 2(x + 1) - 8 = 4x - (3 - x) - 7 ?
En resumen
7x - 2x - 2 = 4x - 3 + x - 7 7x - 2x - 4x - x = 2 - 3 - 7 7x - 6x = 2 - 10 x = - 8.
7x - 2x - 2 = 4x - 3 + x - 7
7x - 2x - 4x - x = 2 - 3 - 7
7x - 6x = 2 - 10
x = - 8.
