1 > 11 + 5x
- 10 > 5x
5x < - 10
x < - 2

As you have read, you switch the > to < when you divide by a negative number. Just in case you do not believe them, you can do the problem differently to get the same answer.

-5x+1>11 subtract 11 and add 5x to both sides
-10>5x divide by 5
-2>x

x< -2


-5x+1>11
-5x>10
-divide both sides by -5. doing this flips the < to a >.
x<-2

-5x+1-1>11-1
-5x>10
x<-2
When u multiply/divide both sides of an inequality by a negative, the inequality switches. i.e. -10x>10 (x<-1

Which ever way you choose or what ever is way less complicated to paintings with. a great style of persons placed letters on the left and numbers on the properly suited. in basic terms try to be consistent. 5x - 11 = x + 21 4x-11 = 21 4x = 32 divide the two facets via 4 x=8 5x - 11 = x + 21 -11 = -4x +21 -32 = -4x divide the two facets via -4 x=8 the two way could be properly suited

this is very easy if you just know the steps.

i'm sure you've heard of PEMDAS... well with inequalities you do NOT use it!!!

first you will subtract 1 from both sides so that you have all of the variables (the X's) on one side and the regular numbers on the other side.

this will give you -5X>10

now you need to divide by -5 on both sides to get the X by itself. BUT you must remember that when you multiply or divide by a negative number the inequality SWITCHES SIGNS.

so we have -5X>10
divide both sides by -5
X>-2

but now we switch the sign!!
so the final answer is:

X<-2



done.
