Make Q the subject of formula if p = (frac{M}{5})(X + Q) + 1

A.
(frac{5P – MX + 5}{M}) 
B.
(frac{5P – MX – 5}{M}) 
C.
(frac{5P + MX + 5}{M}) 
D.
(frac{5P + MX – 5}{M})
Correct Answer: Option B
Explanation
p = (frac{M}{5})(X + Q) + 1
P – 1 = (frac{M}{5})(X + Q)
(frac{5}{M})(p – 1) = X + Q
(frac{5}{M})(p – 1) x = Q
Q = (frac{5(p 1) – Mx}{M})
= (frac{5p – 5 – Mx}{M})
= (frac{5p – Mx – 5}{M})
