Hey mate, you could solve this equation by
Sending the -7 over to the other side, so you can make x by itself,
You equation should like
X=-7*-3
You have multiple because you sent it over when it was dividing with x, when you send anything over the sign changes to the opposite sign.
You then multiply both the factors and you get
X=21 positive because 2 negatives is equal to a positive .

Answer #3 | 08/02 2014 00:08

x=21
we want to get x by itself. in order to that multiply both sides of the equation by -7, this gets rid of the fraction on the left side of equation and only left with x on left side. then -3 times -7=21.

Positive: 66.666666666667 %

Answer #4 | 08/02 2014 00:12

x / (-7) = (-3)
x = (-7) (-3)
x = 21

Positive: 60 %

Answer #5 | 08/02 2014 03:21

X = 21

Positive: 50 %

Answer #6 | 08/02 2014 00:09

here it goes
x/(-7)=-3
x= -3*(-7)
x= 21
21/(-7)=-3
:)

Positive: 50 %

Answer #7 | 08/02 2014 00:06

x-7=-3
+7=+7
x=4
Add a positive 7 to the other side
Add -3+7
x=4

Positive: 50 %

Answer #8 | 09/02 2014 18:52

x/(- 7) = - 3
- x/7 = - 3
=> Cancel the -ve sign from both sides, then
x/7 = 3
=> Multiply both sides by 7, i.e.
x/7 * 7 = 3 * 7
7x/7 = 21
x = 21 ...Ans.

Positive: 50 %

Answer #10 | 08/02 2014 00:14

21 is the right answer
x divided by -7 equals -3
x equals -7*-3
x equals 21
