Solution for (6x+8y-z)-(7x-y+5z)= equation:


Simplifying
(6x + 8y + -1z) + -1(7x + -1y + 5z) = 0

Remove parenthesis around (6x + 8y + -1z)
6x + 8y + -1z + -1(7x + -1y + 5z) = 0
6x + 8y + -1z + (7x * -1 + -1y * -1 + 5z * -1) = 0
6x + 8y + -1z + (-7x + 1y + -5z) = 0

Reorder the terms:
6x + -7x + 8y + 1y + -1z + -5z = 0

Combine like terms: 6x + -7x = -1x
-1x + 8y + 1y + -1z + -5z = 0

Combine like terms: 8y + 1y = 9y
-1x + 9y + -1z + -5z = 0

Combine like terms: -1z + -5z = -6z
-1x + 9y + -6z = 0

Solving
-1x + 9y + -6z = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-9y' to each side of the equation.
-1x + 9y + -9y + -6z = 0 + -9y

Combine like terms: 9y + -9y = 0
-1x + 0 + -6z = 0 + -9y
-1x + -6z = 0 + -9y
Remove the zero:
-1x + -6z = -9y

Add '6z' to each side of the equation.
-1x + -6z + 6z = -9y + 6z

Combine like terms: -6z + 6z = 0
-1x + 0 = -9y + 6z
-1x = -9y + 6z

Divide each side by '-1'.
x = 9y + -6z

Simplifying
x = 9y + -6z
