SALUT !

Răspuns:

a. 7x + 6x = -2

13x = -2

× = -2/13

b. - rad 3x = rad 27

x= -9

c. x= - 60

d. 3×X rad 2 - x rad 2 =3 (căci acești radicali se omit ,taie)

e. 2rad3 × 2x + 1 - 3rad 3 × 1 - 2x = 10rad3x - 15 + 4

10rad3x= -11 - 2rad3 -1 - 3rad3

10rad3x= -12 -5rad3

x= -12 -5rad3 / 10 rad3

×= -12 ×1pe 2

×= -6

SUCCES!!!
