math problem?

Question

If (x+1)/(-2) > 3 then:

do anybody have solution for this?

thanks!

Answer 1

sure....
(x+1) < -2*3
x < -7

Answer 2

(x+1)/divide both parts on the left by -2:
(-x/2) +(-1/2) >3 i moved the negative sign to the top of the fraction because that is the way it would be written.
now you can multiply everything by 2:
-x -1 >6
& move the -1 to the other side:
-x > 7
x< -7

Answer 3

x has to be a negative number so that being
divided by a negative number will become positive, right?

so it has to be more than -2 x 3 -1
x < -7 (meaning -8, -9, -10 etc)

e.g., -8+1/-2 = -7/-2 = 3.5 which is greater than 3

tadaa!

Answer 4

(x+1)/(-2) > 3
cross multiply...but since you multiply 3 by (-2), you have to reverse the inequality symbol..so...

x+1 < -6

then,

x < -7

Answer 5

first of all you can make them equal
(x+1)/(-2)=3
then solve for "x"
x+1=-6
x=-7
=> for this question x < -7
it means for any value x is smaller than -7 this equation is correct

have a nice day

Answer 6

multiply both sides by -2

(x+1)< -6

now subtract 1 from both sides

x< -7

Answer 7

(x+1)/(-2) > 3
i.e, x+1 < -6
i.e, x < -7
