x-5\times 2=8
Consider the first equation. Insert the known values of variables into the equation.
x-10=8
Multiply -5 and 2 to get -10.
x=8+10
Add 10 to both sides.
x=18
Add 8 and 10 to get 18.
z=18
Consider the third equation. Insert the known values of variables into the equation.
a=18
Consider the fourth equation. Insert the known values of variables into the equation.
x=18 y=2 z=18 a=18
The system is now solved.
