Question

4 log(3x + 1 ) = 2
log (x + 3) = log 2

Answer 1

4 log(3x+1) = 2
4² = 3x+1
16 = 3x+1
16-1 = 3x
15 = 3x
15/3 = x
5 = x

log (x+3) = log 2
x+3 = 2
x = 2-3
x = -1

Answer 2

log(3x+1)=log16⇒matikan 4log
                             3x+1 =16
                             3x=15⇒x=5
log(x+3)=log2⇒matikan log⇒x+3=2⇒x=-1
