If 4 - x > 5, then?
- x > - 1
- x < - 1
- x > 1
- None of these
Explanation
To solve the inequality 4-x>5, you need to isolate the variable x.
Subtract 4 from both sides of the inequality: 4-x-4>5-4
-x>1
Multiply both sides by -1.
When you multiply or divide an inequality by a negative number, you must reverse the inequality sign.
(-1)(-x)<(-1)(1)
x<-1
