Make m the subject of the relation: q = \;1/3(m+n) h

Correct Answer is : m= 3qh−nm = \;3q/h - nm=h3q−n

Correct Answer is : m= 3qh−nm = \;3q/h - nm=h3q−n

Make

m

q = \;\frac{1}{3}(m+n) h

Solution:

q = \;\frac{1}{3}(m+n) h

Get rid of the denominator by multipliying both sides of the equation by the denominator, 3

\;3 \times q = 3 \times \;\frac{1}{3}(m+n) h

\;3 q = 1(m+n) h

Divide both sides of the equation by

h

\;\frac{3q}{h} = m+n

Make

m

the subject,

n

goes to the other side of the equation.

\;\;\frac{3q}{h} - n = m

\;m = \;\frac{3q}{h} - n
