Answer :
Answer:
-15
Step-by-step explanation:
you start by collecting like terms which will be
-x=20-5.
which is -x=15
divide both sides by -1
therefore the Ans=-15
Answer: x > -15
===============================
Work Shown:
-x+5 < 20
-x+5-5 < 20-5 ... subtract 5 from both sides
-x < 15
-x/(-1) > 15/(-1) ... divide both sides by -1
x > -15
Note how the inequality sign flips when we divide both sides by a negative number.
-----------
Alternative method
-x+5 < 20
-x+5+x < 20+x ... add x to both sides
5 < 20+x
5-20 < 20+x-20 ... subtract 20 from both sides
-15 < x
x > -15
We get the same answer.
