Answer 1

Ответ:

-10

Пошаговое объяснение:

-5х+5у=5*(у-х) =5*(-2) =-10

Answer 2

Ответ:

-4х-(х-5у)=-4х-х+5у=-5х+5у=5*(у-х)      5*(-2)=-10

Answer 3

To simplify the expression, let's first substitute the value of y-x into the expression:

y - x = -2

Now, rearrange the equation to express y in terms of x:

y = x - 2

Now, replace y in the expression with the above value:

-4x - (x - 5y)

= -4x - (x - 5(x - 2))

Now, distribute the negative sign inside the parentheses:

= -4x - x + 5(x - 2)

Now, distribute the 5:

= -4x - x + 5x - 10

Now, combine like terms:

= (5x - x - 4x) - 10

= 0x - 10

Since 0x is equal to 0, the simplified expression is:

-10
