We have an equation with parentheses. To make our lives easier, first get rid of the parentheses. We do this by using the distributive property.
It is used like this: a(b + c) = ab + ac.
Use the distributive property on the left-hand side.
3(x - 1) = 6
3x - 3 = 6
Now we have an equation that is easier.
The x variable is being multiplied by 3 and added to -3.
Reverse all of these operations with their inverse operation.
3x - 3 = 6
3x = 9 <--- I got rid of the -3 term by using the inverse of subtraction. Addition.
                  And I did the same for both sides to keep the equation true.
x = 3 <--- The inverse of multiplication is division.
                So, I divided both sides by 3.
So, x is equal to 3.
        
             
        
        
        
Tax code- Bible = 18528
tax code + Bible = 21472
add the two together to get 
2* tax code = 18528 + 21472
tax code = 20000

?/22=61/70
Move 22 over the equal sign
?=61*22/70
?=1342/70
?=19.1714286

Hope this helps!
        
             
        
        
        
When dividing 1/8 by 2
we have to first take the reciprocal of 2 
reciprocal is when the numerator and denominator are exchanged
2 when written as a fraction is 

we need to find the reciprocal of 

 which is 

then 

when 'of' function is used it means to multiply the 2 fractions 
when multiplying fractions multiply the numerators by numerators and multiply denominators by denominators 
is 

answer is
