Question

solve for x: log3(2x-5)=log3(x+4)

Answer 1

x=9

Answer 2

See when you have:
\[\large \log_x(a) = \log_x(b)\]

This implies :
\[\large \color{green}{a = b}\]

So apply this in your question, you will get:
\[\large 2x- 5 = x + 4\]

Solve for x here..

1. Add 5 both the sides first.
2. Subtract x from both the sides, and you will get your x..

Answer 3

log3(2x-5)=log3(x+4)
log(2x-5)/log3 = log(x+4)/log3
log(2x-5)=log(x+4)
appyling antilog
antilog(log(2x-5))=antilog(log(x+4))
2x-5 = x+4
2x-x = 4+5
x=9(ans..)
