6a-11=13

add 11 to both sides  cross out -11 with +11 
 13+11 =24
6a=24   
divide 6 on both sides  
 a= 4

Since it’s -11 you add 11 to get zero, add 11 to 13 and get 24 bring down the 6A, put 6A equals 24, Then divide by six on both sides the six crosses out left with a variable so a equals 24÷6 which is four so A equals four
