Answer:
x=3
Step-by-step explanation:
In(x-1) = In(6) - In(x)
In(x-1) + In(x) = In(6)
In((x-1)x) = In(6)
In(x^2-x) = In(6)
x^2-x=6
x^2-x-6=0
x^2+2x-3x-6=0
x(x+2)-3(x+2)=0
(x-3)(x+2)=0
x=3 because x=-2 need to be cancel out
Answer:
x= 1/3 , -4/3
Step-by-step explanation:
9x^2 + 9x -4 =0
(3x-1) (3x+4) =0
x= 1/3 , -4/3
No the answer is 89 because 97 - 8 is 89
