Question

4a-2 ≤a+1 ≤3a+4 please show steps?

Answer 1

Huh? the question is \[4a -2\le a +1\le 3a +4\] and I'm supposed to get something like x such as x is less than or equal to BLANK less than or equal to BLANK

Answer 2

4a -3 < a < 3a + 3

Answer 3

subtract 1 through out the inequallity

Answer 4

yeah i did that but i keep getting stuck

Answer 5

jm has done this for u

Answer 6

With what o.o

Answer 7

thats complete?????

Answer 8

this is complete, but u can get x coz there is no x :P

Answer 9

in the back of the book they ended up with -3/2 < a <1 ( < is less than or equal to )

Answer 10

4a-3<a
3a<3
a<1
next
a<3a+3
-2a<3
a>-3/2
or -3/2<a
combine both

Answer 11

-3/2<a<1 :)

Answer 12

thanks, I just could not figure it out but i thought whatever you did to one side you did everywhere and what you did on the first one isnt the same on the second

Answer 13

oh, if u r confused, u can ask

Answer 14

actually u have to split up to sides

Answer 15

on the first you did -1 then - a and +3 then divide by three
but the second you did -1 then -3a then divide by negative 2

Answer 16

4a-2 ≤a+1 ≤3a+4
4a-2 ≤a+1 and a+1 ≤3a+4

Answer 17

see i thought if you did for example minus three you did it to bothe the first and second part

Answer 18

now solve them seperatley

Answer 19

no yeah i got you... im just saying i was confused because i thought if i did minus a on the left one i had to do minus a on the right
thank you both
