Question

Solve the equation of log (2x + 4) = log (3x -12).

Answer 1

x=16

Answer 2

thanks :) how did you solve that?

Answer 3

I use an app. It's called Mathway helps out a lot

Answer 4

oh :D

Answer 5

log (2x + 4) = log (3x -12)
the value of a number does not change when expressed differently
example 5*2 = 10 and 6 + 4 = 10 means 5*2 = 6 + 4 10 is still 10
so for this problem .2x + 4 = 3x - 12
solve for x
variable to one side
divide by coefficient of variable
keep the balance of the equation

any questions?
