write an example of an equation with variables on each side. state the steps you would use to isolate the variable.
+13 2x + 5y = y + 7x
to isolate x:
Minus y from both sides
2x + 4y = 7x
Minus 2x from both sides
4y = 5x
divide equation by 5
\(x = {4y \over 5}\)
to isolate y:
Minus y from both sides
2x + 4y = 7x
Minus 2x from both sides
4y = 5x
divide equation by 4
\(x = {5x \over 4}\frac{}{}\)
