Question 253582
Here is the question
{{{12+1/3a=20}}}
I don't know if a is in the numerator or denominator.
--
case 1: in numerator.
{{{12+(1/3)a=20}}}
step 1 - multiply by 3 to get
{{{36+a=60}}}
step 2 - subtract 36 to get
{{{a=24}}}
--
case 2:
{{{12+1/(3a)=20}}}
step 1 - multiply by 3a to get
{{{36a+1=60a}}}
subtract 36a to get
{{{1=24a}}}
divide by 24 to get
{{{1/24 = a}}}
