Question 1175233
<font color=black size=3>
{{{M = W + (1/3)L^2}}}


{{{M - W = (1/3)L^2}}} Subtract M from both sides


{{{(1/3)L^2 = M - W}}} Flip both sides (left and right sides swap places)


{{{L^2 = 3(M - W)}}} Multiply both sides by 3


{{{L = sqrt(3(M - W))}}} or {{{L = -sqrt(3(M - W))}}} Apply the square root. Don't forget about the plus/minus.


If your teacher only wants one equation for L, then I'd go with {{{L = sqrt(3(M - W))}}}
