2x +3 per 3x -2x -3per 4x

[tex]2x + \frac{3}{3x} - 2x - \frac{3}{4x} = \frac{3}{3x} - \frac{3}{4x} [/tex]
penjelasan = 2x - 2x = 0 (habis)
jadi sisanya :
[tex] \frac{3}{3x} - \frac{3}{4x} [/tex]
jadi kali silang ya...

[tex](3 \times 4x) - (3x \times 3) = (12x) - (9x)[/tex]
[tex]12x - 9x = 3x [/tex]
[tex]x = 3[/tex]
*selesai*
