.2...........3........5....
Bare glem alle punktumene...de betyr ikke no!

Slik jeg tolker det, er likningen
[tex]\frac{x \:-\: 2}{2} \:+\: x \;=\; \frac{7x \:+\: 6}{3} \:-\: \frac{4(x \:+\: 4)}{5}[/tex] (ganger med 2*3*5 = 30)
15(x - 2) + 30x = 10(7x + 6) - 24(x + 4)
15x - 30 + 30x = 70x + 60 - 24x - 96
45x - 30 = 46x - 36
46x - 45x = 36 - 30
x = 6.
