Simplify the following expression: 5x - 6y 5z - x - 12y 2z 6x - 18y 7z 4x - 18y 7z 4x - 6y 7z 6x - 6y 7z

Simplify step-by-step.

5x - 6y (5) z - x - 12y (2) z (6) x - 18y (7) z (4) x - 18y (7) z (4) x - 6y (7) z (6) x - 6y (7) z

= 5x + - 30y z + - x + - 144x y z + - 504x y z + - 504x y z + - 252x y z + - 42y z

Combine Like Terms:

= 5x + - 30y z + - x + - 144x y z + - 504x y z + - 504x y z + - 252x y z + - 42y z

= ( - 144x y z + - 504x y z + - 504x y z + - 252x y z) + ( - 30y z + - 42y z) + (5x + - x)

= - 1404x y z + - 72y z + 4x
