I'm not sure does anyone else know the answer?
[ 2x + y = -9 ] x -3
[- 3x +11= y ] x 2
-6x -3y = 27
-6x + 22 = 2y
-6x +27 = 3y
-6x +22 = 2y
5 = y
-6x -3x5 = 27
-6x -15 = 27
-6x = 42
-x = 42/6
-x = 7
x = -7
answer
x = -7
y = 5
Well, first, you need to know what you want to 'do' to it.
You want to find the description of what 'x' has to be in order to
make that inequality a true statement. Here's one way to do it:
4/5 x > 14
Multiply each side by 5 : 4 x > 70
Divide each side by 4 : x > 17.5 .
That's it. As long as 'x' is more than 17.5 ,
the original inequality is true.

Answer: 4 and 12
Step-by-step explanation:
Let x be the "another number"
Therefore, "one number" is 1/3x
1/3 x + x = 4/3 x
4/3 x = 16
1/3 x = 4
x = 12
Therefore, the numbers are 4 and 12.
