AMP Parsing Error of [(x � 2)/4 � 1/5 = (7x + 1)/20]: Invalid expression. Closing bracket expected �2)/4�1/5=(7\x+1)/20 at /home/ichudov/project_locations/algebra.com/templates/Algebra/Expression.pm line 187. .

multiply this equation by 20, then we get:
5*(x - 2) - 4 = 7x + 1
<=> 5x - 10 - 4 = 7x + 1
<=> 5x - 7x = 1 + 10 + 4
<=> -2x = 15
then we get x = -15/2
