Question

4x − (x + 3) при x = −5

Answer 1

Ответ:

4 * (-5)  - (-5 + 3) = -20 - (-2) = -20 + 2 = -18

Answer 2

To evaluate the expression 4x - (x + 3) when x = -5, we simply substitute -5 for x in the expression and simplify as follows:

4x - (x + 3) = 4(-5) - (-5 + 3) = -20 - (-2) = -18

Therefore, when x = -5, the value of the expression 4x - (x + 3) is -18.
