y=8-7
Consider the first equation. Subtract 7 from both sides.
y=1
Subtract 7 from 8 to get 1.
1+8=z
Consider the second equation. Insert the known values of variables into the equation.
9=z
Add 1 and 8 to get 9.
z=9
Swap sides so that all variable terms are on the left hand side.
y=1 z=9
The system is now solved.
