Yes, you're right.
2(7x) = -70
7x = -70/2
7x = -35
x = -35/7
x = -5

Yes
2(7x)=-70
14x=-70
x=-5
2*7*(-5)=-70
14*(-5)=-70
-70=-70

Pretty good guess!
There are lots of ways to get there:
2(7x)/7 = -70/7 (divide both sides by 7)
2x = -10
2x/2 = -10/2
x = -5

Yes. it is -5
how?..
SOLUTION:
[there are many ways on how to solve it. here's one..]
2(7x) = -70
7x = -70/2
7x = -35
x = -35/7
x = -5
another way is....
2(7x) = -70
14x = -70
x= -70/14
x= -5
CHECKING:
*just substitute the value of x to the given equation...
x=-5
2(7x) = -70
2[ (7) (-5) ] = -70
2(-35)= -70
-70= -70
*if both sides of the equation are equal , then your answer is correct.
in this case.. yes.. the answer is -5..:)

Yes, the answer is -5.
First you divide both sides by 2 leaving:
7x= -35
Then you divide both sides by 7 leaving:
x= -5

yes that is correct because you multiply 2 and 7x together to get
14x = -70
then you divide -70 by 14
x = -70/14
x = -5
you are right :)
