If x = 3 is the solution of the equation a (X-7) / 3 = A / 7X + 6 about X, find the value of A

If x = 3 is the solution of the equation a (X-7) / 3 = A / 7X + 6 about X, find the value of A

X = 3 is the solution of the equation a (X-7) / 3 = A / 7X + 6 about X
Then a * (3-7) / 3 = A / 7 * 3 + 6
-4/3a=3/7a+6
Multiply both sides by 21 and you get
-28a=9a+126
-28a-9a=126
-37a=126
a=-126/37
