x=110+\frac{0\times 1}{2}
Consider the first equation. Subtract 150 from 260 to get 110.
x=110+\frac{0}{2}
Multiply 0 and 1 to get 0.
x=110+0
Zero divided by any non-zero number gives zero.
x=110
Add 110 and 0 to get 110.
y=150+110
Consider the second equation. Insert the known values of variables into the equation.
y=260
Add 150 and 110 to get 260.
z=260
Consider the third equation. Insert the known values of variables into the equation.
a=260
Consider the fourth equation. Insert the known values of variables into the equation.
x=110 y=260 z=260 a=260
The system is now solved.
