Simplifying
log(x + -7) + log(x + -5) = -1log(5)

Reorder the terms:
glo(-7 + x) + log(x + -5) = -1log(5)
(-7 * glo + x * glo) + log(x + -5) = -1log(5)
(-7glo + glox) + log(x + -5) = -1log(5)

Reorder the terms:
-7glo + glox + glo(-5 + x) = -1log(5)
-7glo + glox + (-5 * glo + x * glo) = -1log(5)
-7glo + glox + (-5glo + glox) = -1log(5)

Reorder the terms:
-7glo + -5glo + glox + glox = -1log(5)

Combine like terms: -7glo + -5glo = -12glo
-12glo + glox + glox = -1log(5)

Combine like terms: glox + glox = 2glox
-12glo + 2glox = -1log(5)

Reorder the terms for easier multiplication:
-12glo + 2glox = -1 * 5glo

Multiply -1 * 5
