Question 125261
You didn't have parentheses in your equation.
Is this what you meant?
{{{(w + 4)/8 = (w + 10)/5}}}
{{{5(w + 4) = 8(w + 10)}}}
{{{5w+20=8w+80}}}
{{{-3w=60}}}
{{{w=-20}}}
Check your answer.
{{{(w + 4)/8 = (w + 10)/5}}}
{{{(-20 + 4)/8 = (-20+ 10)/5}}}
{{{(-16)/8=(-10)/5}}}
{{{-2=-2}}}
True statement.
Good answer.
