Answer:
IT is not
Step-by-step explanation:
Let's replace. If it's a solution, it means that BOTH equations has to be true.
[tex]\left \{ {{-10=-5(-24)+22} \atop {-2(-24) +6(-10)=-12} \right.[/tex]
Now, the second equations seems good - [tex] 48-60 =-12[/tex] indeed.
First alas isn't. RHS is 142, which is totally not the same as -10.
