x=25-2
Consider the second equation. Subtract 2 from both sides.
x=23
Subtract 2 from 25 to get 23.
23+y=29
Consider the first equation. Insert the known values of variables into the equation.
y=29-23
Subtract 23 from both sides.
y=6
Subtract 23 from 29 to get 6.
6+z=2
Consider the third equation. Insert the known values of variables into the equation.
z=2-6
Subtract 6 from both sides.
z=-4
Subtract 6 from 2 to get -4.
x=23 y=6 z=-4
The system is now solved.
