The solution is (x, y, z) = (2.5, 1, 2.5).
It is a singular matrix.

The solution is (x, y, z) = (2.5, 1, 2.5).
It is a singular matrix.
6+z = 3 z = 3-6 z = -3

3x + 2 = 82
Problem:z/(z + 2) = 30/42Simplify right hand side by dividing both denominator and numerator by 6:z/(z + 2) = 5/7You should see that if z equals 5:5/(5 + 2) = 5/7Simplify:5/7 = 5/7Answer:z equals 5.
(z - 6)(z - 6)
z = -80
