3sqrt%284x%29-1=3%29
3sqrt%284x%29-1%2B1=3%2B1%29
3sqrt%284x%29=4%29
%283sqrt%284x%29%29%2F3=4%2F3%29
%28sqrt%284x%29%29=4%2F3%29
%28%28sqrt%284x%29%29%5E2%29=%284%2F3%29%5E2%29 square both sides to eliminate the radical]
4x=16/9
4x/4=(16/9)(1/4)
x=4/9
.
.
Check by plugging x=4/9 back into the original equation.
