Answer:

X=10

Step-by-step explanation:

Plug 3 into the k in the first equation. Multiply by 3 to cancel out the fraction. This leaves you with x-1=9. Add 1 to both sides and you get x=10.

X - the number

$2x+x-18=-30-x \\
3x-18=-30-x \\
3x+x=-30+18 \\
4x=-12 \\
x=\frac{-12}{4} \\
x=-3$

The number is -3.
