Given:
The expressions 3x - 4y - 7z, x - 3y + 2z and -4x + 9y -11 z
To find:
Subtract 3x - 4y - 7z from the sum of x - 3y + 2z and -4x + 9y -11 z
Solution:
From given, we have,
The expressions 3x - 4y - 7z, x - 3y + 2z and -4x + 9y - 11 z
Firstly, find the sum of x - 3y + 2z and -4x + 9y - 11 z
= (x - 3y + 2z) + (-4x + 9y - 11 z)
= x - 3y + 2z - 4x + 9y - 11z
= -3x + 6y - 9z
Secondly, Subtract 3x - 4y - 7z from -3x + 6y - 9z
= (3x - 4y - 7z) - ( -3x + 6y - 9z)
= 3x - 4y - 7z + 3x - 6y + 9z
= 6x - 10y + 2z
Therefore, the value of "Subtract 3x - 4y - 7z from the sum of x - 3y + 2z and -4x + 9y -11 z" is 6x - 10y + 2z
