You can
put this solution on YOUR website!well, I made a mistake:here is the correct answer (it should be 5/10 not 2/10)
5/10(26x/10-4)+23/10(14x/10-5)=130x/20-20/10+322x/20-115/10=
=452x/20-135/10= (226x-135)/10=22.6x-13.5
If you meant your problem to be an equation than:
226x/10-135/10=0
187x=135
x=0.72
sorry
