Question

Tell whether the ordered pair is a solution of the linear system (-24,-10)

Answer 1

IT is not

Explanation:

Let's replace. If it's a solution, it means that BOTH equations has to be true.

`\left \{ {{-10=-5(-24)+22} \atop {-2(-24) +6(-10)=-12} \right.`

Now, the second equations seems good -
`48-60 =-12` indeed.

First alas isn't. RHS is 142, which is totally not the same as -10.
