Find the value of the argument that makes the linear function y = 3x + 2 equal to 11.

Based on the data from the assignment condition, we write everything in the form of an equation:

3x + 2 = 11;

Let’s rewrite the equation by transferring 2 through the equal sign, changing the sign from “+” to “-“:

3x = 11 – 2; we make the necessary calculations with respect to x:

3x = 9;

Divide both sides of the equation by 3 and get:

x = 3.
