z=2\times 8+3\times 3-8
Consider the third equation. Insert the known values of variables into the equation.
z=16+9-8
Do the multiplications.
z=25-8
Add 16 and 9 to get 25.
z=17
Subtract 8 from 25 to get 17.
a=17
Consider the fourth equation. Insert the known values of variables into the equation.
x=8 y=3 z=17 a=17
The system is now solved.
