6×-11=5 ;; 3×+9=7×-2 ;; 5×+3=11-4×-6 ;;2 (×-3)=3-5× ;,3×-9+4×-2=15-6×-3 ;;va rog frumos ajutatima .

Answer 1

6x-11=5
6x=5+11
6x=16
x=16/6
x=4/3

3x+9=7x-2
3x-7x=-2-9
-4x=-11
x=11/4

5x+3=11-4x-6
5x+3=5-4x
5x+4x=5-3
9x=2
x=2/9

2(x-3)=3-5x
2x-6=3-5x
2x+5x=3+6
7x=9
x=9/7

3x-9+4x-2=15-6x-3
7x-11=12-6x
7x+6x=12+11
13x=23
x=23/13
