Question

(2/3q – 3/4) and (–1/6q – r) What is the coefficient of q in the sum of these two expressions?

Answer 1

The co-efficient of q in sum of the given expression is 2

Explanation:

Given expressions are
`\frac {2}{3q}-\frac {3}{4}` and
`(-1)/(6q)-r`

Now sum the given expression

`\frac {2}{3q}-\frac {3}{4} + (-1)/(6q) -r = (4-1)/(6q) -(3)/(4) -r`

`\frac {2}{3q}-\frac {3}{4} + (-1)/(6q) -r = (3)/(6q) -(3)/(4) -r`

`\frac {2}{3q}-\frac {3}{4} + (-1)/(6q)-r =(1)/(2q) - (3)/(4) -r`

Here the co-efficient q is 2 (since
`(1)/(q) = (1)/(2)` )
