Question 647790
 5y -2(y-5)=19
 according to BODMAS rule, we will first open the bracket
 5y -2y +10 =19     {{-2)*(-5); Here we are multiplying two negative number,so the  answer will be positive, +10}
 3y +10 = 19
 Now subtract 10 from both the sides
 3y +10 - 10 =19 -10       
           
 3y = 9              To get the value of 'y', we need to separate it from 3 but 
                     here 3 is neither added nor subtracted to 'y' ,rather it is 
                     multiplied to 'y'. In this case when we shift 3 to the 
                     opposite side of the 'equal to' sign ,it will be divided 
                     there.
  y= 9/3
  y= 3
