Answer 1

Por definición de logaritmo

[x - 2)/(2x - 5)] + 35 = 6^2 = 36

(x - 2)/(2x - 5) = 36 - 35 = 1

x - 2 = 2x - 5

x - 2x = - 5 + 2

- x = - 3

x = 3  respuesta

Tomando logaritmos

(2x + 3)log7 = 3log2

2x + 3 = 3(log7/log2)

log7 = 0.8451    /     log2 = 0.3010

2x + 3 = 3[(0.8451)/(0.3010)] = 8.4230

2x = 8.4230 - 3 = 5.4230

x = (5.4230)/2

x = 2.7115  respuesta
