Question

What is the coefficient of q in the sum of (2/3q-3/4) and(-1/6q-r)?

Answer 1

The coefficient is 1/2

Explanation:

sorry don't have time to do it but it definitely is 1/2

Answer 2

The coefficient is
`(1)/(2)`

Explanation:

The given sum is

`((2)/(3)q -(3)/(4))+(-(1)/(6)q-r)`

We can choose to add only the coeffients of
`q` or simplify the whole sum.

`=(2)/(3)q -(1)/(6)q-(3)/(4))-r)`

We collect the LCM for the
`q` terms;

`=(4-1)/(6)q-(3)/(4))-r)`

This will give us;

`=(3)/(6)q-(3)/(4))-r)`

Which is the same as

`=(1)/(2)q-r-(3)/(4)`

The coefficient is
`(1)/(2)`
