3x-x=15
Consider the first equation. Multiply both sides of the equation by 3.
2x=15
Combine 3x and -x to get 2x.
x=\frac{15}{2}
Divide both sides by 2.
y=\frac{15}{2}-\frac{15}{2}
Consider the second equation. Insert the known values of variables into the equation.
y=0
Subtract \frac{15}{2} from \frac{15}{2} to get 0.
z=0
Consider the third equation. Insert the known values of variables into the equation.
x=\frac{15}{2} y=0 z=0
The system is now solved.
