    yes... 11z-3-7z=9 means (11-7)z-3 = 9 which gives 4z-3 = 9; Now do you want to solve for z?

    well let us get moving fromwher you got stuck..... equality has a property that if you add or subtract or multiply or divide by same number on both side of equality the result won't be altered.... so.... that is a+b =x is same as a+b+c= x+c a+b-c= x-c (a+b)*c= x*c (a+b)/c = x/c

    yes you can find a number which satisfies your rlation by using above property of equality

    yes... the method you followed is a round about way...but there is an alternate simple 100% guarntry way using the above property wanna learn it?

    :) so aftr simplification of 11z-3-7z=9 we got 4z-3 = 9 now add 3 to both sides of equality ( the result will not change because of the property a+b =x is same as a+b+c= x+c) what you get
