Step by step
One sixth of the sum 1/6 ( + )
the sum of d and 3 1/6 (d+3)
minus the product 1/6 (d+3) - ( )( )
The product of 4 and q 1/6 (d+3) - 4q
The product of p and 3 3p
is subtracted from - 3p
three-fourths of s 3/4 s - 3p
three-fourths the sum 3/4 ( + )
the sum of 9 and k 3/4 (9+k)
Obviously, the final line in each case is the answer.
