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

A.

5P−MX+5/M

B.

5P−MX−5/M

C.

5P+MX+5/M

D.

÷(5P+MX-5)/M

Correct Answer: 5P−MX−5/M

Explanation

p = M/5(X + Q) + 1 P - 1 = M/5(X + Q) 5/M(p - 1) = X + Q 5/M(p - 1)- x = Q Q = 5(p−1)−Mx/M = 5p−5−Mx/M = 5p−Mx−5/M

p = M/5(X + Q) + 1 P - 1 = M/5(X + Q) 5/M(p - 1) = X + Q 5/M(p - 1)- x = Q Q = 5(p−1)−Mx/M = 5p−5−Mx/M = 5p−Mx−5/M
