Answer: y = 8/p+q+4
Solution
Step 1:
take all the y variables on one side of the equation
so,
py+qy+4y = 8
(NOTE: -4y when shifted towards the LHS of the equation, it coinages it's sign so it goes from negative to positive)
Step 2:
Take y common
y (p+q+4) = 8
Step 3:
Since the questions requires it to be solved in terms of y.
y = 8 / p+q+4
