Question

log (x+3)=log(7-4x)

how to solve that?

Answer 1

do you have an iphone

Answer 2

There is a rule that if you have the same base then the values inside are equal. For example if log(a)=log(b) then it follows that a=b. From their you just solve for x.

Answer 3

so it will be x+3=7-4x
x+4x=7-3
5x=4
x=0.8

Answer 4

Yeah :)
