Question

Solve the given inequality and graph it on the number line

-3x + 9 < 15

Answer 1

Is there a common factor among those numbers that you see?

Answer 2

it is 16>15

Answer 3

jk

Answer 4

leave the term with the unknown on one side and move everything else to the other side
divide by the coefficient of the unknown term
do the same to each side to maintain the balance

Answer 5

the thing is we have to change it from adding a negative to subtracting a positive

Answer 6

what is the term with the unknown?

Answer 7

15 ? sorry im a little bit confused

Answer 8

Treat this sort of like a normal equation in the sense that everything you do to one side of this expression is done to the other.

Isolate the 'x' by subtracting 9 to get rid of 9 from the left hand side.
Then from there you can work it out YAY

Answer 9

so like move the 9 to the other side and subtract that from 15 ? @wcrmelissa2001

Answer 10

Yes.

Answer 11

yes

Answer 12

YEAHHHHHHHHH :D

Answer 13

ohh okay. so -3 + 9 = 12. 15 - 9 is 6.

12>6

Answer 14

no -3x in the original not like terms

Answer 15

Ohhh

Answer 16

keep the x there! that's what you're supposed to solve

Answer 17

how about reading my response above

Answer 18

the term with the unknown is -3x

Answer 19

yes and you want to leave by itself that is why you subtracted 9.
because you want to maintain the balance that is why you also subtracted 9 from the right side

Answer 20

proceed with the next step

Answer 21

ohh so -3x - 9 instead of -3x + 9 ?

Answer 22

do you know what the coefficient is?

Answer 23

nope
