Resuelvanlo es urgente Log (x+3) - log (×-6)=1

Answer 1

Resuelvanlo es urgente Log (x+3) - log (×-6)=1

log (x + 3) - log (x - 6) = 1
log₁₀ (x + 3) - log₁₀ (x - 6) = 1
log₁₀ (x  +3) = 1 + log₁₀ (x  - 6)
log₁₀ (x + 3) = log₁₀ (10¹) + log₁₀ (x - 6)
log₁₀ (x + 3) = log₁₀ (10 (x - 6))
x + 3 = 10 (x  -6)
x + 3 = 10x - 60
x - 10x  = - 60 - 3
- 9x = - 63
x = - 63/-9
x = 7

Rpt. El valor de x es 7
