Question

rezolvati ecuatiile a.3x plus 2 egal 6x minus 4 b.1 supra 8 plus x supra 2 egal x supra 4 plus 5 supra 6 VA ROG MULTTTTTTTTTTTTTTTTTTT!!!!!!!!!!!!

Answer 1

a)

3x+2=6x-4

3x-6x=-4-2

-3x=-6

x=-6/-3

x=6/3   ⇒   x=2

b)

1/8+x/2=x/4+5/6    - aducem la acelasi numitor .... 24...

3/24+12x/24=6x/24+20/24  - eliminam numitorul prin inmultire cu 24

3+12x=6x+20

12x-6x=20-3

6x=17    ⇒   x=17/6
