The answer57-56-z-7 equals 757z-6 plus 4-50?

Answer 1

If your equation was written correctly your answer should be z = (23/379)

The solution is as follows:

57-56-z-7 = 757z-6+4-50

-z-6=757z-52

-z-6+52=757z-52+52

-z+46=757z

-z+46+z=757z+z

46=758z

(46/758)=(758z)/758

(46/758)=z

(23/379)=z
