You can put this solution on YOUR website! Distribute the 2/9 first so you have
2/9 x - 12/63 = 1/63x + 40/63
Then multiply both sides by 63 (the common denominator) to get rid of the fractions
14x - 12 = x + 40
Subtract x from both sides
13x - 12 = 40
Add 12 to both sides
13x = 52
Divide both sides by 13
x = 13
