Answer:
Keeping in mind the 'x' is in numerator, i got the answer to be 6.
Step-by-step explanation:
2/7x + 1/2x = 40/7 - 1/6x
2/7x + 1/2x + 1/6x = 40/7
2/7x + (3+1)/6x = 40/7
2/7x + 4/6x = 40/7
2/7x + 2/3x = 40/7
(23)+(27) / (73)x = 40/7
(6+14) / 21x = 40/7
20/21x = 40/7
20x = 4021/7
20x = 403
x = 403 /20
x = 2*3
x=6
