Question

1+2/3*x=1,5+1/6*x x=Q
0,5x+2/9=3(5)-1/2x;x=Q
5/3*(x+2)=10(3);x=Q+

Answer 1

1+2/3*x=1,5+1/6*x
1+2/3*x=15/10+1/6*x
1+2/3*x=3/2+1/6*x  I6 numitorul comun

6/6+4/6*x=9/6+1/6*x

6+4*x=9+x

4x-x=9-6

3x=3

x=1=>x=1/1




0,5x+2/9=3(5)-1/2x

5/10x+2/9=32/9-1/2x

1/2x+2/9=32/9-1/2x

9x+4=64-9x

9x+9x=64-4

18x=60

x=60/18=>x=10/3

x=3,(3)


5/3*(x+2)=10(3)

5/3*(x+2)=93/9

15(x+2)=93

15x+30=93

15x=93-30

15x=63

x=63/15

x=4,2
