Make Q the subject of formula if p frac M 5 X Q... - JAMB Mathematics 2010 Question
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 option: b
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})
