Sorry guys but i really need to know how to solve this too

The answer is x < -1

Step-by-step explanation:

The first step is to subtract 9 from both sides of the equation.

9 - x > 10 ---> 9-(9) -x > 10-(9) ---> -x > -1

Next, multiply both sides of the equation by -1.

-x > -1 ---> -x(-1) > -1(-1) ---> x < -1

The answer is x < -1

Thing to note:

When you multiply an inequality by a negative number, then greater or lesser than sign flips and the constant stays the same.

just sum

10 + 10 = 20
