Which graph would solve the equation 5log(x+3)=5

Too bad you haven't shared the graphs yet.however, this problem can be solved algebraically: if 5 log (x+3) = 5, we can simplify things by div. both sides by 5: log (x+3) = 1.  now use these quantities as exponents of the base 10, as                          follows:       log (x+3)            110                    = 10            which results in x+3 = 10, so that x=7 (answer)
