Question

6. What should be subtracted from the sum of 3p + 4q – 9r and 3r + 13q – 8p such that the result is 2p + 2q + 2r?​

Answer 1

Answer:

15q-7p-8r

Step-by-step explanation:

sum:

17q-5p-6r

in order to get the result of 2p+2q+2r, consider each term

17q-x=2q

x=15q

-5p-x=2p

x=-7p

-6r-x=2r

x=-8r

therefore 15q-7p-8r must be subtracted
