use the oneone property to solve the equation for x e3x536So

use the one-one property to solve the equation for x. e3x+5=36

onet- to - one property : f(a)=f(b) if and only if a=b

e^(3x+5) = 36

Taking log on both sided

ln( e^(3x+5)) = ln(36)

Writing ln(36) in expoenetial form : ln36 = lne^ln36

So, ln(e^(3x+5) = lne^ln36

From 1-1 property: 3x+5 = ln36

x = (ln36 -5)/3

x= -0.472 (solution)
