Question
Solution 1
The given equation is (5a - 3b) : (4a - 2b) = 2 : 3.
We can simplify this equation by dividing both sides of the equation by 2. This gives us:
(5a - 3b) / (4a - 2b) = 2 / 3.
Cross multiplying gives us:
3*(5a - 3b) = 2*(4a - 2b).
Expanding both sides gives us:
15a - 9b = 8a - 4b.
