Question

15.(x-7)+27-11=raiz de 144 +14

Answer 1

$15.(x-7)+27-11= \sqrt{144} +14 \\ \\ 15x-105+27-11=12 +14 \\ \\ 15x= 12+14+105-27+11 \\ \\ 15x= 115 \\ \\ x= \frac{115}{15}\to \boxed{x= \frac{23}{3} }$

Espero que te sirva, salu2!!!!

Answer 2

15 (x - 7) + 27 - 11 = √144 + 14

15x - 105 + 27 - 11 = 12 + 14

15x - 105 - 11 + 27 = 12 + 14

15x - 116 + 27 = 12 + 14

15x - 89 = 26

15x = 26 + 89

15x = 115

x = 115/15---simplificamos la quinta 

x = 23/3

Solución : 

x = 23/3
