Question 21004
(x+1)ln2 = xln5


First use the distributive property:
x ln2 + ln 2 = x ln5


As in all simple equation solving, get all the x terms on one side, so subtract x ln2 from each side:
{{{x ln2-x ln2 + ln2 = x ln5 - x ln2}}}

{{{ ln 2 = x ln5 - x ln 2}}}


In order to get the x in one place, you must factor out the common factor of x on the right side:
{{{ln 2 = x (ln5 - ln2) }}}


Divide both sides by (ln5 - ln2):

{{{(ln 2)/((ln5 - ln2)) = (x (ln5 - ln2))/((ln5 - ln2)) }}}

{{{x = (ln 2)/((ln5 - ln2)) }}}
{{{x= 0.7565 }}} approximately
