y=1-9
Consider the first equation. Subtract 9 from both sides.
y=-8
Subtract 9 from 1 to get -8.
z=-8
Consider the second equation. Insert the known values of variables into the equation.
a=-8
Consider the third equation. Insert the known values of variables into the equation.
b=-8
Consider the fourth equation. Insert the known values of variables into the equation.
y=-8 z=-8 a=-8 b=-8
The system is now solved.
