3+y=4
Consider the second equation. Insert the known values of variables into the equation.
y=4-3
Subtract 3 from both sides.
y=1
Subtract 3 from 4 to get 1.
z=2\times 3+3\times 1
Consider the third equation. Insert the known values of variables into the equation.
z=6+3
Do the multiplications.
z=9
Add 6 and 3 to get 9.
a=9
Consider the fourth equation. Insert the known values of variables into the equation.
x=3 y=1 z=9 a=9
The system is now solved.
