3x+3=0
Consider the first equation. Combine x and 2x to get 3x.
3x=-3
Subtract 3 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-3}{3}
Divide both sides by 3.
x=-1
Divide -3 by 3 to get -1.
y=-1
Consider the second equation. Insert the known values of variables into the equation.
z=-1
Consider the third equation. Insert the known values of variables into the equation.
x=-1 y=-1 z=-1
The system is now solved.
