Question

Need help with figuring out if this is a system of equations

Answer 1

Given:

The system is:

`\begin{cases}{2x+3y+10z=9} \\ {-x+2y+5z=1} \\ {3x+z=5}\end{cases}`

The solution is (2,3,-1)

Find-:

The (2,3,-1) is the solution of function or not

Explanation-:

The solution is (2,3,-1) which means:

`\begin{gathered} x=2 \\ \\ y=3 \\ \\ z=-1 \end{gathered}`

Check the value for the given expression:

`\begin{gathered} 2x+3y+10z=9 \\ \\ 2(2)+3(3)+10(-1)=9 \\ \\ 4+9-10=9 \\ \\ 3\\e9 \end{gathered}`

So, it is not a solution of system.
