Question

4(5x-3y) -6(3x-y) если 3x-y=2, 1

Answer 1

Ответ:

-17,4

Пошаговое объяснение:

4(5x-3y) -6(3x-y) если 3x-y=2, 1

4(5x-3y) -6(3x-y)

20х-12х-18х+6у

20х-30х+6у

-10х+6у

3x-y=2, 1

-10×3+6×2,1

-30+12,6=-17,4

Answer 2

To find the value of the expression 4(5x-3y) - 6(3x-y) when 3x-y = 2, we'll substitute the given value of 3x-y into the expression and simplify it.

Let's substitute 3x-y = 2 into the expression:

4(5x-3y) - 6(3x-y) = 4(5x-3y) - 6(3x-y)

Now, let's simplify the expression:

= 4(5x-3y) - 6(3x-y) = 20x - 12y - 18x + 6y (applying distributive property) = (20x - 18x) + (-12y + 6y) = 2x - 6y

So, the simplified expression is 2x - 6y when 3x - y = 2.
