Question

(4t-6+5t)+(9-5t+-2t)=7t-(1-6t) comprobación

Answer 1

Respuesta:

(4t-6+5t)+(9-5t+-2t)=7t-(1-6t)

4t+5t-5t-2t-7t-6t=6-9-1

-11t= -4

t= 4/11

(4*4/11-6+5*4/11)+(9-5*4/11+-2*4/11)=7*4/11-(1-6*4/11)

16/11-6+20/11+9-20/11-8/11=28/11-(1-24/11)

16/11-6+20/11+9-20/11-8/11= 28/11+13/11

41/11= 41/11

espero te sirva
