infinite many solutions
when the expressions are simplified, the variables will disappear and a true statement like -25=-25 or 0=0 is left. this means that there are an infinite many of solutions to solve the equation.
any number substitute for x will satisfy the equation.
simplifies to = 4/5
multiply by 2/2
or 80 %
