Question

У = 3 - 2х. Якщо x = -3 то у = ...​

Answer 1

у = 3 - 2х. Якщо x = -3, то у = 3 - 2 * (-3) = 3 + 6 = 9

Answer 2

Task: Evaluate the expression u = 3 - 2x. If x = -3, what is the value of u?

To evaluate the expression u = 3 - 2x, we substitute the value of x with -3 and calculate the value of u.

Let's substitute x = -3 into the expression:

u = 3 - 2(-3)

Simplifying the expression:

u = 3 + 6

u = 9

Therefore, if x = -3, the value of u is 9.
