24\xi +E=400
Multiply both sides of the equation by 4.
E=400-24\xi
Subtract 24\xi from both sides.
24\xi +E=400
Multiply both sides of the equation by 4.
24\xi =400-E
Subtract E from both sides.
\frac{24\xi }{24}=\frac{400-E}{24}
Divide both sides by 24.
\xi =\frac{400-E}{24}
Dividing by 24 undoes the multiplication by 24.
\xi =-\frac{E}{24}+\frac{50}{3}
Divide 400-E by 24.
