Пошаговое объяснение:

=4х-6+3у=4*(-1)-6+3*(-4)=-4-6-12=-22

Answer 2

Ответ:

4*(-1)-3*2+4=-6

-4-6=-10

-10+4=-6

Answer 3

To find the value of the expression 4x - 3(2 - y) when x = -1 and y = -4, you simply need to substitute the given values into the expression and perform the calculations.

Let's plug in the values:

x = -1 y = -4

Now, substitute the values into the expression:

4(-1) - 3(2 - (-4))

Now, simplify the expression step by step:

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

Now, the expression becomes:

-4 - 3(6)

Next, perform the multiplication:

-3(6) = -18

Finally, calculate the result:

-4 - (-18) = -4 + 18 = 14

So, when x = -1 and y = -4, the value of the expression 4x - 3(2 - y) is 14.
