Question 5797
you really must learn to use brackets - you confuse the hell of everyone by your "English" descriptiion of the maths question.


I am assuming (big assumption) that you mean the following:


{{{sqrt(j) + sqrt(j) + 14 = 3sqrt(j) + 10}}}? If so,


{{{2sqrt(j) + 14 = 3sqrt(j) + 10}}}
{{{2sqrt(j) + 4 = 3sqrt(j)}}}
{{{4 = sqrt(j)}}}
or ... {{{sqrt(j) = 4}}} --> square both sides to give {{{j = 4^2}}}.


j = 16
