(7w + 4x) + -1(3w + -1z) + (x + z) = 0

Remove parenthesis around (7w + 4x)
7w + 4x + -1(3w + -1z) + (x + z) = 0
7w + 4x + (3w * -1 + -1z * -1) + (x + z) = 0
7w + 4x + (-3w + 1z) + (x + z) = 0

Remove parenthesis around (x + z)
7w + 4x + -3w + 1z + x + z = 0

7w + -3w + 4x + x + 1z + z = 0

Combine like terms: 7w + -3w = 4w
4w + 4x + x + 1z + z = 0

Combine like terms: 4x + x = 5x
4w + 5x + 1z + z = 0

Combine like terms: 1z + z = 2z
4w + 5x + 2z = 0

Solving
4w + 5x + 2z = 0

Solving for variable 'w'.

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

Add '-5x' to each side of the equation.
4w + 5x + -5x + 2z = 0 + -5x

Combine like terms: 5x + -5x = 0
4w + 0 + 2z = 0 + -5x
4w + 2z = 0 + -5x
Remove the zero:
4w + 2z = -5x

Add '-2z' to each side of the equation.
4w + 2z + -2z = -5x + -2z
