Question

Please verify
Solve log(1-x) = log10
(1-x) = 10
-x = 9
X=9

Answer 1

if -x = 9 then x = -9 (not +9)
you could solve
-x = 9 by multiplying both sides by -1
(or divide both sides by -1, or add -9 to both sides, then +x to both sides)

Answer 2

Missed typing the negative sign , is -9 correct to make log(1-(-9)= log(10)

Answer 3

yes. 1 - -9 is 1+9 = 10
