15. (x-7) +3³-11= √144+7²

Answer 1

15 (x - 7) + 3³ - 11 = √144 + 7²

15x - 105 + 27 - 11 = 12 + 49

15x - 105 - 11 + 27 = 12 + 49

15x - 89 = 12 + 49

15x - 89 = 61

15x = 61 + 89

15x = 150

x = 150/15

x = 10

Solución : 

x = 10

VERIFICAMOS : 

15 (x - 7) + 3³ - 11 = √144 + 7²

15 (10 - 7) + 3³ - 11 = √144 + 7²

15 (3) + 27 - 11 = 12 + 49

45 + 27 - 11 = 12 + 49

72 - 11 = 61

61 = 61

Listo.
