A) 5X-X=11-3 ; 4X=8 ; X=8/4 ; X=2 ; B) 8X-3X=-20 ; 5X=-20 ; X=-20/5 ; X=-4 ; C) √3X +2√3X=1-4 ; 3√3X=-3; X=-3/3√3; X=-√3/3
Explicație pas cu pas:
Explicație pas cu pas:
a)5x-x=-3+11
4x=8/:4
x=2
b)8x+20=3x
8x-3x=-20
5x=-20 /:5
x=-4
c)x radical 3 + 2x radical 3=1-4
3x radical 3 = -3 / :3 radical 3
x=-3/3 radical 3
x= - 3 radical 3/9
x= - radical 3/3
