-9v=169-7
Consider the first equation. Subtract 7 from both sides.
-9v=162
Subtract 7 from 169 to get 162.
v=\frac{162}{-9}
Divide both sides by -9.
v=-18
Divide 162 by -9 to get -18.
x=162
Consider the third equation. Subtract 7 from 169 to get 162.
z=162
Consider the fifth equation. Insert the known values of variables into the equation.
v=-18 w=1.2 x=162 y=1.2 z=162
The system is now solved.
