4x+z+14x=0
Add 14x to both sides.
18x+z=0
Combine 4x and 14x to get 18x.
18x=-z
Subtract z from both sides. Anything subtracted from zero gives its negation.
\frac{18x}{18}=-\frac{z}{18}
Divide both sides by 18.
x=-\frac{z}{18}
Dividing by 18 undoes the multiplication by 18.
z=-14x-4x
Subtract 4x from both sides.
z=-18x
Combine -14x and -4x to get -18x.
