Question

-5/6*(1,8x-6/5y)-2,1*(-16/7x+16/3y)

Answer 1

Ответ:

3,3х - 10,2у.

Пошаговое объяснение:

- 5/6•(1,8x - 6/5y) - 2,1•(-16/7x + 16/3y) = - 1,5х + у + 4,8х - 11,2у = 3,3х - 10,2у.

Answer 2

To simplify the expression -5/6(1.8x - 6/5y) - 2.1(-16/7x + 16/3y), you can follow these steps:

1. Distribute the constants (-5/6 and -2.1) to the terms inside the parentheses:

-5/6 * 1.8x + 5/6 * (6/5)y - 2.1 * (-16/7x) + 2.1 * (16/3y)

2. Perform the multiplications:

(-15/10)x + (30/30)y + (336/70)x - (336/15)y

3. Simplify the fractions:

(-3/2)x + y + (48/7)x - (224/15)y

4. Combine like terms by adding the x terms and the y terms:

(-3/2 + 48/7)x + (1 - 224/15)y

5. To combine the fractions with different denominators, find a common denominator, which is 30:

(-45/30 + 240/30)x + (30/30 - 448/30)y

6. Add the fractions:

(195/30)x + (-418/30)y

7. Reduce the fractions if possible:

(13/2)x - (209/15)y

So, the simplified expression is (13/2)x - (209/15)y.
