Question

Rezolvati in R inecuatia:

$\frac{3x + 11}{6} + \frac{x - 7}{2} < \frac{5x - 1}{12} - 2 \frac{1}{6}$
Va rog rezolvare completa!

Answer 1

( 3x + 11 )/6 + ( x - 7 )/2 < ( 5x - 1 )/12 - 2 1/6
( 3x + 11)/6 + ( x - 7 )/2 < ( 5x - 1 )/12 - 13/6
2( 3x + 11 ) + 6( x - 7 ) < 5x - 1 - 26
6x + 22 + 6x - 42 < 5x - 27
12x + 22 - 42 < 5x - 27
12x - 20 < 5x - 27
12x - 5x - 20 < - 27
12x - 5x < - 27 + 20
7x < - 27 + 20
7x < - 7
x < - 7 : 7
x < - 1
