21 ...va rog mult , e urgent ...vreau rezolvarile complete ...dau coroana

Answer 1

a) x(3+2/2)+3/2(x+2/2) = /2(2/2-x)-1
Eliminam parantezele
3x+2/2x+3/2x+12=4-/2x-1
Reducem termenii asemenea
Scazi
3x+5/2x+12=3-/2x
3x+5/2x+/2x=3-12
3x+6/2x=-9
(3+6/2)x =-9
x= -9 supra 3+6/2
x= - 9 supra 3(1+2/2)
x=-3 supra 1+2/2
x=- 3(1-2/2) supra -7
x=-3-6/2 supra -7
x= 3-6/2 supra 7

c) x(7+4/3)+2(2+/3)=2/3(2x+1) -3

7x+4/3x+4+2/3=4/3x+2/3-3

7x+4=-3

7x=-3-4

7x=-7

x=-1


Doar pe astea leam putit face deocamdata
