Question

4 + x/2 > 2x
How do I solve it?
Please and Thank you!

Answer 1

4 + x/2 > 2x
multiply both sides by 2 to get
4 + x > 4x
bring x over
4> 4x - x
4 >3x
4/3 > x

Answer 2

You multiplied both sides by 2 but still have 4 on the left side?

Answer 3

i saw it as (4 + x)/2

Answer 4

4 + x/2 > 2x
4 + x/2 >4x/2
4 > 4x/2 - x/2
4 >(4x - x)/2
4 > 3x/2
4*2 > 3x
8 > 3x
8/3 > x

Answer 5

I don't know which one it is either

Answer 6

well i guess the writer will have to verify

Answer 7

@akb48, is it

\[\frac{4 +x}{2} > 2x\] or \[4 + \frac{x}{2} > 2x\]

Answer 8

The second one.

Answer 9

multiply by 2
you get
8 + x > 4x
subtracting x
8 > 3x
dividing by 3
8/3 > x
x < 8/3
\[x \in (-\infty, \frac{ 8 }{ 3 } )\]
