Question

subtract the sum of 15p – 10q + 12z and 9p – 3q + 2z from 19p + 6q + 12z​

Answer 1

Answer:

- 5p + 19q - 2z

Step-by-step explanation:

Sum of 15p - 10q + 12z and 9p - 3q + 2z,

15p - 10q + 12z + 9p - 3q + 2z

= 15p + 9p - 10q - 3q + 12z + 2z

= 24p - 13q + 14z

Subtract the sum of 15p - 10q + 12z and 9p - 3q + 2z from 19p + 6q + 12z​,

19p + 6q + 12z - ( 15p - 10q + 12z + 9p - 3q + 2z )

= 19p + 6q + 12z - ( 24p - 13q + 14z )

= 19p + 6q + 12z - 24p + 13q - 14z )

= 19p - 24p + 6q + 13q + 12z - 14z

= - 5p + 19q - 2z
