Question

What is nine minus x is greater than ten

Answer 1

This can be written as:
9-x>10
-x>1 (subtract 9 from both sides)
x<-1 (divide both sides by -1 and change the inequality sign)

Hope this helps

Answer 2

9-x>10
Subtract 9 from each side
-x>1
Multiply each side by -1 and reverse the inequality sign
x<-1
