Question

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

Answer 1

2x/7-18/7+x/3=3
6x+7x/21=3+18/7
13x/21=21+18/7
x=39/7×21/13
x=9

Answer 2

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

2/7x - 18/7 +x/3 = 3

2/7 x -18/7+1/3 x = 3

2/7x +1/3 x -18/7 = 3

6+7/21 x -18/7 = 3


13/21x -18/7 = 3

13/21 x  = 3+18/7 
13/21 x = 21+18/7

13/21 x = 39 / 7

x = 39/7 / 13/21

x = 39/7*21/13 = 9
