Question

-2y-(-4x+6y) ,якщо x-2=-3​

Answer 1

Ответ:

Пошаговое объяснение:

-2у-(-4х+6у)= -2у+4х-6у=4х-8у=4(х-2)=4*(-3)= -12

Answer 2

To evaluate the expression -2y - (-4x + 6y) when x-2=-3, we first need to find the value of x using the given equation.

Given: x - 2 = -3

To solve for x, add 2 to both sides of the equation:

x = -3 + 2

x = -1

Now that we have the value of x, we can substitute it back into the expression and simplify:

-2y - (-4x + 6y)

Replace x with -1:

-2y - (-4(-1) + 6y)

Simplify the expression within parentheses:

-2y - (4 + 6y)

Now distribute the negative sign inside the parentheses:

-2y - 4 - 6y

Combine like terms:

(-2y - 6y) - 4

-8y - 4

So the simplified expression is -8y - 4.
