Question

Find the numerical co-efficient of q while subtracting 6p-5q+3r from 10p+2q-r.​

Answer 1

Answer:

coefficient of q is 7

Step-by-step explanation:

We have to subtract 6p-5q+3r from 10p-2q-r

so,

(10p+2q-r) - (6p-5q+3r) = 10p+2q-r - 6p + 5q -3r

= (10p-6p) (2q+5q) + (-r-3r)

= 4p+7q-4r

so, coefficient of q is 7
