Subtract L from both sides.
the expression now becomes,
<span>S−L=−rL</span>
2)Divide by L on both sides.
<span><span><span>S−L</span>L</span>=−r</span>
3)Multiply with a negative sign on both sides in the final step to obtain the expression in terms of r so the answer is<span> #(L-S)/L = r#</span>
The answer is A hope this helps
