Question

How do I solve the inequality for this: 10 < 9 + x

Answer 1

Treat like equals
10<9+x
subtract 9 from both sides
1<x
x>1

x is any number greater than 1, not including 1

Answer 2

Subtract 9 from each side of the equation. so you would get 1<x. meaning that any number larger then 1 would correctly solve the equation.
