x=2\times 1
Consider the first equation. Multiply both sides by 1.
x=2
Multiply 2 and 1 to get 2.
y=2
Consider the second equation. Insert the known values of variables into the equation.
z=2
Consider the third equation. Insert the known values of variables into the equation.
a=2
Consider the fourth equation. Insert the known values of variables into the equation.
x=2 y=2 z=2 a=2
The system is now solved.
