2x=6-15
Consider the first equation. Subtract 15 from both sides.
2x=-9
Subtract 15 from 6 to get -9.
x=-\frac{9}{2}
Divide both sides by 2.
y=-\frac{9}{2}
Consider the second equation. Insert the known values of variables into the equation.
z=-\frac{9}{2}
Consider the third equation. Insert the known values of variables into the equation.
x=-\frac{9}{2} y=-\frac{9}{2} z=-\frac{9}{2}
The system is now solved.
