Question

Solve:(-2x-5)+7x>-15

Answer 1

Someone plz help me

Answer 2

\[(-2x-5)+7x>-15\]
\[-2x-5+7x>-15\]
\[7x-2x-5>-15\]
\[5x-5>-15\]
\[5x>-15+5\]
\[5x>-10\]... can you solve from here @Punkchick ?

Answer 3

no

Answer 4

sók, next step is to divide both sides by 5
so 5x/5 = ?
and -10/5 = ?
once you've done that, you'll have your final answer

Answer 5

would it be x<-2??

Answer 6

almost perfect, the symbol doesnt change direction though
so x>-2

Answer 7

Can u help me on a couple more jack 1???

Answer 8

sweet, shoot

Answer 9

Solve: 2 (b-8)>12

Answer 10

you got this one already ;) in the other post

Answer 11

No I don't think so.

Answer 12

\[2 (b-8)>12\] expand out the brackets
\[2b-16>12\] now add 16 to both sides
\[2b>12+16\] now isolate the b by dividing both sides by 2
\[2b>28\]
=...?

Answer 13

14

Answer 14

spot on, so b>14

Answer 15

Solve: 5x-6<9x+30

Answer 16

\[5x-6<9x+30\]
ok i'll tell u the steps, and you do this one, k?
\[5x-6<9x+30\] first, add 6 to both sides

next, minus (9x) from both sides

now you should have all the x numbers on one side, and all the plain numbers on the other side

so finally, divide both sides by whatever number is left in front of the x ... = final answer

now show me ur steps

Answer 17

???\

Answer 18

13,5

Answer 19

Am I I right???

Answer 20

mmm... could u show me the steps u went through, line by line, coz i got a diffrnt answer

Answer 21

I really need to know the answer

Answer 22

Could u plz tell me it

Answer 23

Am I right???

Answer 24

\[5x−6<9x+30\]
first, add 6 to both sides
\[5x−6+6<9x+30+6\]
next, minus (9x) from both sides
\[5x−6+6-9x<9x+30+6-9x\]
now the -6+6 = 0 on the left hand side
and the 9x - 9x= 0 on the right hand side
so...

\[5x-9x<+30+6\]
now you should have all the x numbers on one side, and all the plain numbers on the other side
5x - 9x = ?
and 30 + 6 = ?

so finally, divide both sides by whatever number is left in front of the x ... = final answer

Answer 25

32

Answer 26

5x - 9x = -4x
amd 30 + 6 = 36
so -4x<36
so times both sides by -1 means you flip the direction of the sign
4x>-36
x > -9
