Answer:
x=5,y=1 and z=-2
Step-by-step explanation:
We are given that system of equation
(I equation)
(II equation )
(III equation )
Equation II multiply by 3 then add with equation I
Then, we get
....(Equation IV)
Subtract equation II from equation III then we get
(equation V)
Adding equation IV and equation V then, we get

Substitute x=5 in equation V then, we get




Substitute x=5 and y=1 in equation then, we get




Hence, the solution for the given system of equation is given by
x=5,y=1 and z=-2
Using quadratic formula you can have a maximum of two solutions. When you set this problem equal to zero, your a=-1, b=-10, c=2
