Question

Solve using the multiplication principle~

-7x > (1/15)

The solution set is {x | x ? ? }

Answer 1

The solution is {x | x > -1/105}

Answer 2

- 7x > (1/15) cross multiplying you will get

- 105x > 1  OR 105x < - 1  OR x < [ - 1/105]

Answer 3

Divide both sides by -7... when you divide by a negative number you need to remember to reverse the direction of the sign.

x < (1/15) / (-7)

x < -(1/105)

x < -1/105

Answer:

{ x | x < -1/105 }

Answer 4

-7x>1/15

-x>(1/15)/7

-x>(1/15)*(1/7)

-x>1/105

x<-1/105

Solution {x | x < -1/105 }

Answer 5

since your deviding by a negative the answer is

x< -(1/105)

Answer 6

-7x>1/15

7x<-1/15

x<(-1/15)/7

x<-1/105

...remember whenever you multiply variable "x" by -"this negative sign" you should change the direction,means that change < to > or > to <....."Good Luck"

Answer 7

-7x > (1/15)

(-7*(1/7))x > (1/15)*(1/7)

-x > (1/105)

x < -(1/105)

answer is {x | x < -1/105 }
