5x+4=0
Consider the first equation. Combine x and 4x to get 5x.
5x=-4
Subtract 4 from both sides. Anything subtracted from zero gives its negation.
x=-\frac{4}{5}
Divide both sides by 5.
y=-\frac{4}{5}
Consider the second equation. Insert the known values of variables into the equation.
z=-\frac{4}{5}
Consider the third equation. Insert the known values of variables into the equation.
x=-\frac{4}{5} y=-\frac{4}{5} z=-\frac{4}{5}
The system is now solved.
