5) a si b va rog dau fllw pe tik tok!!!!!!!!!!! E urgent tare

Answer 1

Răspuns:

a)

2x-4/5 + 4x + 14 / 15 = -1/10 + 2x+7/10

6(2x-40 = 2(4x+14) = -3+3(2x+7)

12x-24+8x+28=-3+6x+21

20x+4 = 18 + 6x

20x-6x+4 = 18-4

14x=14

x= 1

b)

($\sqrt{2x}$+3) x 6 = 3(9-$\sqrt{2x}$)

$\sqrt{2x}$=3-2$\sqrt{2x\\}$

2x=9-12$\sqrt{2}$x+8$x^{2}$

x= 1+6$\sqrt{2}$-$\sqrt{1+12\sqrt{2} }$/8
