x=20-10
Consider the first equation. Subtract 10 from both sides.
x=10
Subtract 10 from 20 to get 10.
y=25-3
Consider the second equation. Subtract 3 from both sides.
y=22
Subtract 3 from 25 to get 22.
z+10=40
Consider the third equation. Insert the known values of variables into the equation.
z=40-10
Subtract 10 from both sides.
z=30
Subtract 10 from 40 to get 30.
x=10 y=22 z=30
The system is now solved.
