Question 663567: 2a-5/7 = 3a+4/9
Answer by ReadingBoosters(3246)   (Show Source):
You can put this solution on YOUR website! Starting with
2a - 5/7 = 3a + 4/9
Group like terms
-5/7 - 4/9 = 3a - 2a
Create common denominator on the left
-5/7(9/9) - 4/9(7/7) = a
-45/63 - 28/63 = a
a -73/63 = -1 10/63
...
Proof
2(-73/63) - 5/7 = -146/63 - 5/7(9/9) = -146/63 - 45/63 = -191/63
3(-73/63) + 4/9 = -219/63 + 4/9(7/7) = -219/63 + 28/63 = -191/63
