x-(2)/(5)-x+(3)/(6)=4 Reduce the expression (3)/(6) by removing a factor of 3 from the numerator and denominator. x-(2)/(5)-x+(1)/(2)=4 Since x and -x are like terms, add -x to x to get 0. 0-(2)/(5)+(1)/(2)=4 Combine all similar terms in the polynomial x-(2)/(5)-x+(1)/(2). -(2)/(5)+(1)/(2)=4 Since -(2)/(5)+(1)/(2)$4, there are no solutions. No Solution
