alguien que me ayude, porfaaa​

Answer 1

Respuesta:

(5a + 8b – 5c + 11a – b + c) – (a – 3b)

= (5a + 11a + 8b – b – 5c + c) – (a – 3b)

= (16a + 7b – 4c) – (a – 3b)

= (16a + 7b – 4c) – a + 3b

= 16a – a + 7b + 3b – 4c

= 15a + 10b – 4c ............... rpta 1

= 5(3a + 2b) – 4c .............. rpta 2

= 15a + 2(5b –2c) ............. rpta 3
