Question

Rezolvati ecuatia:g)10(x-3)=4(6x+7)-2
h)(2+radical din 3)x-2+radical din 3=0
i)radical din 3x+4=1-2 radical din 3x

Answer 1

g)10x-30=24x-28-2

10x-24x=-28-2+30

-14×

Answer 2

g) 10x-30=24x+28-2

10x-30=24x+26

10x-24x=26+30

-14x=56

x= -56/14

x= -4

h) (2+V3)x-2= -V3

(2-V3)x= -V3+2

x=(-V3+2)/(-V3+2)

x= 1

i) V3x+2V3x=1-4

3V3x= -3

x= -3/3V3

x= -1/V3 rationalizam cu V3

x= -V3/3
