z=\frac{11}{2}
Consider the first equation. Divide both sides by 2.
y-2\times \frac{11}{2}=-3
Consider the second equation. Insert the known values of variables into the equation.
y-11=-3
Multiply -2 and \frac{11}{2} to get -11.
y=-3+11
Add 11 to both sides.
y=8
Add -3 and 11 to get 8.
z=\frac{11}{2} y=8
The system is now solved.
