5xy - (5 + 3xy) =(5x + 1) - 1 =(4 - x) + x =?

5xy - (5 + 3xy) = (5x + 1) - 1 = (4 - x) + x =.

En resumen

5xy - (5 + 3xy) = 5xy - 5 - 3xy = 2xy - 5 ________________________________________________________ (5x + 1) - 1 = 5x + 1 - 1 = 5x ________________________________________________________ (4 - x) + x = 4 - x + x = 4.
