I'm going to use the substitution method:


Start with the second equation.


Plug in


Distribute


Multiply EVERY term by the LCD 5 to clear out the fraction.


Combine like terms on the left side.


Subtract from both sides.


Combine like terms on the right side.


Divide both sides by to isolate .


Reduce.


Note: the value is part of none of the solutions. So double check the answers or the problem itself.
