Question 675927: be sure to reject any value of x that is not in the domain of the original log expression. give the exact answer. then where necessary use a calculator to obtain the approximation correct to two decimal places for the solution
log(3x-3)=log(x+1)+log4
Answer by lwsshak3(11628) (Show Source): You can put this solution on YOUR website!
log(3x-3)=log(x+1)+log4
log(3x-3)=log[(x+1)*4]
log(3x-3)=log(4x+4)
3x-3=4x+4
x=-7
no solution: (3x-3)>0
