Question

HELP ASAP gold medal will b awarded.solve for X: 3-(2x-5)<-4(x+2

Answer 1

first get rid of the brackets by mult using distributive property

can you do that??

Answer 2

no

Answer 3

-(2x-5) you have to mult by -1 so it changes the signs so =

-2x+5 that is on the right hand side

on the left mult thru by -4

-4x-8


do you see that step??

Answer 4

yes

Answer 5

ok
our equation now read
3-2x+5<-4x-8

we combine like terms on left
-2x+8<-4x-8

now move the x to one side and the constants to the other can you do that??

Answer 6

no

Answer 7

how we do this is to subtract 8 from both sides
remember if we do it to one side we must do it to the other.

-2x+8-8<-4x-8-8 or
-2x<-4x-16

can you guess what we will do next??

Answer 8

divide?

Answer 9

no add 4x to both sides

Answer 10

oh

Answer 11

what do you get??

Answer 12

so -2x<20?

Answer 13

-2x<-4x-16
4x-2x<4x-4x-16

or

2x<-16 here is where we would divide by 2

2x/2<-16/2
now we have x alone

x<-8

Answer 14

oh..

Answer 15

thanks

Answer 16

good job!!
