Answer:

x < - [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Given

[tex]\frac{1}{2}[/tex] x + [tex]\frac{1}{4}[/tex] > [tex]\frac{3}{2}[/tex] x + [tex]\frac{3}{4}[/tex]

The lowest common multiple of 2 and 4 is 4

Multiply through by 4 to clear the fractions

2x + 1 > 6x + 3 ( subtract 2x from both sides )

1 > 4x + 3 ( subtract 3 from both sides )

- 2 > 4x ( divide both sides by 4 )

- [tex]\frac{2}{4}[/tex] > x

- [tex]\frac{1}{2}[/tex] > x , thus

x < - [tex]\frac{1}{2}[/tex]
