Question 985804

{{{3sqrt(2x^2-7)= y/z}}}... make {{{x}}} the subject of the formula

{{{sqrt(2x^2-7)= (y/z)/3}}} 

{{{sqrt(2x^2-7)= (y/3z)}}}.........square both sides

{{{(sqrt(2x^2-7))^2= (y/3z)^2}}}

{{{2x^2-7= (y/3z)^2}}}

{{{2x^2= (y/3z)^2+7}}}

{{{x^2= ((y/3z)^2+7)/2}}}

{{{x= sqrt(((y/3z)^2+7)/2)}}}
