Answer:
✓ (-1,9) is a solution of the inequality x<16-y.
Why?
[tex] \: \: \: \: \: \: \: \: \: \: \: \: x < 16 - y \\ \: \: \: \: \: \: \: \: \: - 1 < 16 - 9 \\ - 1 < 7[/tex]
> You need to substitute the value of x and y to the inequality to see whether it is a solution or not. Then, simplify.
> The solution shows that -1 is less than 7. Therefore, the statement is true and (-1,9) is a solution of the inequality.
