Question

5х-(х+2) при х=-6 Нелп

Answer 1

5x-(x+2)= 5x-x-2=4x-2= 4×(-6)-2=-24-2=-26

Ответ: -26

Answer 2

To evaluate the expression 5х-(х+2) when x = -6, we simply substitute x with -6 in the expression and perform the calculation.

So, let's replace x with -6:

5*(-6) - (-6 + 2)

Now, follow the order of operations (PEMDAS - Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction):

5*(-6) is equal to -30, and -(-6 + 2) is equal to -(6 - 2) which is -4.

Now the expression becomes:

-30 - (-4)

Now, remember that subtracting a negative number is the same as adding the positive number. So, we have:

-30 + 4

Now, perform the addition:

-26

So, when x = -6, the expression 5х-(х+2) evaluates to -26.
