Pas cu pas cum se rezolvă...... ​

Answer 1

d) x - 3x-2/5 < 2( 3 - x ) + x/6 + 11/10

2( 3 - x ) = 2 × 3 - 2x =6 - 2x

x - 3x-2/5 < 6 - 2x + x/6 + 11/10

( 6 + 11/10 numitor comun = 60+11/10 = 71/10 )

x - 3x-2/5 < 71/10 - 2x + x/6 / × 30

30x - 6( 3x - 2 ) < 213 - 60x + 5x

30x - 18x - 12 < 213 - 60x + 5x

30x - 18x + 12 < 213 - 55x

12x + 12 < 213 - 55x

schimb semnele

12x + 55x  <  213 - 12

67x < 201

x < 201 : 67

x < 3
