Subtract 3xy+5yz-7zx from 5xy-2yz-2zx+10xyz.
We have to subtract 3xy+5yz-7zx from 5xy-2yz-2zx+10xyz.
5xy-2yz-2zx+10xyz-3xy+5yz-7zx=5xy-2yz-2zx+10xyz-3xy-5yz+7zx=5xy-3xy-2yz-5yz+7zx-2zx+10xyz=2xy-7yz+5zx+10xyz
Therefore the required answer is 2xy-7yz+5zx+10xyz.
(1) Subtract the sum of 3a and 4a from 9a
(2) Subtract (−5xy + 9yz) from (3xy − 4yz)
(3) Subtract (7m2 − 2m) from (−4m − 7m2)
(4) Subtract (6a − 4b + c) from (−a + 3b − 5c)
(5) Subtract (−4x − 8y + 7) from (3y − 7x + 1)
(6) How much should be added to (5x − 3y) to get (3x − 5y)?
