The first answer is x=12 and the second answer is x=-10
I got this but adding 14 to both sides of the first equation to isolate x there and subtracting 9 from both sides of the second equation to, again, isolate x

Answer:

[tex]x - 14 = - 2 \\ x = - 2 + 14 \\ x = 12 \\ \\ 9 + x = - 1 \\ x = - 1 - 9 \\ x = - 10[/tex]
