Question

5/2<4x-3<= 8/3

Answer 1

Welcome to OpenStudy!

When dealing with an equation between two inequalities, you have to deal with them equally.
The first step is to add +3 to each side

3+5/2 < 4x <= 3+8/3

Does that first step make sense?

Answer 2

are u sure??

Answer 3

I am. Do you have a question about it?

Answer 4

well thanks for answering

Answer 5

Oh you're not done yet. You then have to divide 4 to each side.

Answer 6

but why sould i add +3 before 5/2 and 8/3??

Answer 7

It doesn't matter if it's before or after. It's all commutative from the commutative property.

Answer 8

wait shouldnt i do 5/2<4x-3/2??

Answer 9

5/2<4x-3<= 8/3
is short for two separate relations

5/2 < 4x -3
and

4x - 3 ≤ 8/3

Answer 10

yes
how can u solve it??

Answer 11

how can i solve 5/2<4x-3
???

Answer 12

for the first equation, do as Kirby was showing (though he was solving both at the same time... which you can do if you are an expert)

5/2<4x-3

the idea is to add +3 to both sides, like this:
3+ 5/2 < 4x -3 + 3
now simplify both sides
can you do that ?
