Question

4y/5(y-3)-5x/2(y-3)​

Answer 1

Объяснение:

4y/5(y-3)-5x/2(y-3)=(4y*2-5x*5)/10(y-3)=

=(8y-25x)/10(y-3)

Answer 2

To simplify the expression, we can first factor out the common term of (y - 3) from both fractions in the expression:

4y/5(y-3) - 5x/2(y-3) = (4y)/(5(y-3)) - (5x)/(2(y-3))

Next, we need to find a common denominator for the two fractions. The least common multiple of 5 and 2 is 10, so we can multiply the first fraction by 2/2 and the second fraction by 5/5 to get:

(4y)/(5(y-3)) * 2/2 - (5x)/(2(y-3)) * 5/5 = (8y)/(10(y-3)) - (25x)/(10(y-3))

Now that we have a common denominator, we can combine the two fractions by subtracting the second fraction from the first:

(8y - 25x)/(10(y-3))

So the simplified expression is (8y - 25x)/(10(y-3)).
