Add 4 to both sides.
An inequality is treated just like an equation, except the carat (<) is reversed when multiplying by a negative number.
How do you solve In (x - 4) < 6?
3 answers
Add 4 to both sides
x-4+4<6+4
x<10
x-4+4<6+4
x<10
huh? Does no one see that "ln" there?
ln(x-4) < 6
since e^x is increasing, a<b ==> e^a < e^b
x-4 < e^6
x < 4+e^6
ln(x-4) < 6
since e^x is increasing, a<b ==> e^a < e^b
x-4 < e^6
x < 4+e^6
