First Equation:

Multiply -1 to both the sides and tell me what you get??
And take care, when we multiply both the sises by (-1), Inequality sign reverses..
Solve and tell me what you got?

Answer 2

Till here Solve and tell me what you got?

Answer 9

6>-42 or 4>-4

Answer 10

We will solve first and then second..
First equation is:

-6b > 42

Now, multiply (-1) both sides and just tell me what you got?

Answer 11

6>-42

Answer 12

Where has b gone?

Answer 13

I don't understand

Answer 14

See,
\[(-1) \times (-6b) > (-1) \times 42\]

Solve and tell me what you will get?

Answer 15

6>-42

Answer 16

6b>-42

Answer 17

Yes now you are right..

Now once you multiply by (-1) change the inequality sign..
Tell me what is the inequality sign there?

Answer 18

6b<-42

Answer 19

Yes till here you are right..

Now divide by 6 both the sides and get the value of b.
What you got?

Answer 20

b=-7

Answer 21

How = ???

I think there is an inequality sign there..

Answer 22

b<-7

Answer 23

Yes so you have done with first equation..
Now we will go for second..
4b > -4

Simply divide it by 4 and tell me what you got.

Answer 24

b>-1

Answer 25

Yes now you have two values of b and that is the answer..

b < -7 or b > -1
