Question 750868
(1/3)(9x-12)=4x-9 first this is the normal equation
you need to multiply 1/3 and 9 and next the same with 1/3 and 12 , also you need to simplify 1/3(9)= 1 times 9= 9 and 3 divide 9 = 3 ... 1/3(12)= 1 times 12= 12 and 12 divide 3= 4 .. 
3x-4= 4x-9 now 3x mines 4x = -1x 
 -1x-4=-9 -9 plus -4 = -5 
   -1x=-5 -1x divide -5 = 5  
     x=5 the answer is positive because when you divide 2 negatives numbers the answer become to positive
