Answer:
The co-efficient of q in sum of the given expression is 2
Step-by-step explanation:
Given expressions are [tex] \frac {2}{3q}-\frac {3}{4} [/tex] and [tex] \frac{-1}{6q}-r [/tex]
Now sum the given expression
[tex] \frac {2}{3q}-\frac {3}{4} + \frac{-1}{6q} -r = \frac{4-1}{6q} -\frac{3}{4} -r [/tex]
[tex] \frac {2}{3q}-\frac {3}{4} + \frac{-1}{6q} -r = \frac{3}{6q} -\frac{3}{4} -r [/tex]
[tex] \frac {2}{3q}-\frac {3}{4} + \frac{-1}{6q}-r =\frac{1}{2q} - \frac{3}{4} -r [/tex]
Here the co-efficient q is 2 (since[tex]\frac{1}{q} = \frac{1}{2}[/tex] )
