Question

Subtract the sum of 13x - 11y
+ 9z and - 7z + 3x - 5y from the sum of 6x - 7y - 5z , - 4x + 6z
- 9y and 5x - 4y + 3z


Please give step by step explanation. ​

Answer 1

Answer:

-9x - 4y + 2z

Step-by-step explanation:

Sum to be subtracted from:

= (6x - 7y - 5z) + (-4x + 6z - 9y) + (5x - 4y + 3z)

= (6x - 4x + 5x) + (-7y - 9y - 4y) + (-5z + 6z + 3z)

= 7x - 20y + 4z

Sum to be subtracted:

= (13x - 11y + 9z) + (-7z + 3x - 5y)

= (13x + 3x) + (-11y - 5y) + (9z - 7z)

= 16x - 16y + 2z

Result of the subtraction:

= (7x - 20y + 4z) - (16x - 16y + 2z)

= (7x - 16x) + (-20y + 16y) + (4z - 2z)

= -9x - 4y + 2z
