Answer 2

Given:

• 7xy+5yz-3zx

• 4yz+9zx-4y

• -3zx+5x-2xy

To Find:

• The addition of the given numbers.

Solution:

• We are using the basic algebraic method to add the given numbers.
• 7xy+5yz-3zx+4yz+9zx-4y-3zx+5x-2xy
• Sorting the given number in terms of their like variables we get,
• 7xy-2xy+5yz+4yz -3zx-3zx+9zx-4y+5x
• On simple addition of the above number we get,  5xy+9yz-4y+5x.
• If we want we can further simplify the obtained answer and write in the form y(5x+9z)-4y+5x.
• We just took out the 'y' term from the first two variables and rearranged the expression.

The answer is 5xy+9yz-4y+5x
