Question 176965
Solve for S:
{{{(S-3)/7 = (S+5)/9}}} Multiply both sides by 7 and by 9.
{{{9(S-3)*cross(7)/cross(7) = 7(S+5)*cross(9)/cross(9)}}} Cancel as indicated.
{{{9(S-3) = 7(S+5)}}} Perform the distributive property.
{{{9S-27 = 7S+35}}} Add 27 to both side.
{{{9S = 7S+62}}} Subtract 7S from both sides.
{{{2S = 62}}} Divide both sides by 2.
{{{highlight(S = 31)}}}
