Question

subtract 6xy-5xy-9zx from 11xy-3yz-4zx+10xyz​

Answer 1

Answer:

5xy + 2yz + 5zx + 10xyz

Step-by-step explanation:

Assuming that the second term of the first expression is -5yz, Below is the solution.

When we say 'Subtract a from b', we do b - a.

Hence, in this case :

(11xy-3yz-4zx+10xyz) - (6xy-5xy-9zx)

= 11xy-3yz-4zx+10xyz - 6xy + 5yz + 9zx

Pairing up same terms,

= xy(11 - 6) + yz(-3 + 5) + zx(-4 + 9) + 10xyz

= xy(5) + yz(2) + zx(5) + 10xyz

= 5xy + 2yz + 5zx + 10xyz
