x : 1/7+1/6 =8/9
x : ( 1/7+6/7) =8/9
1/7: ( x+ 4/7 )= 13/5
3/7:(x-1/9 )=4/5
2/7 : 1/4 - 1/7
7/11 x 0 + 5/9 : 1/2
( 3/7 + 1/4 ) : 3/4
4/3 x 1/2 + 7/2 : 1/4
1. 4 + x = 7 - 2x
2. 5 + x = 8,3 + 4,7 - x
3. x + 12 = 35 + ½x
4. 6 + x = 7⅓ + 2 - x
5. 20x + 4 = 19,2 + 15x
6. x + 5 = 8 2/5 - 4x
7. 3 (x +1) = 13,5
8. 32 - (32 - x) = 32
9. 5x - 12 3/5 = 0
10. x - 10/3 = 0
