Question

you’re trying to find the value of y that makes $y = 3 + 2x$ true when $x = 2$. let’s find an $(x, y)$ pair that makes $y = 3 + 2x$ true. when $x = 2$, what is $y$? start by substituting 2 for $x$. \\\

$$\begin{cases} y = 3 + 2x \\\\ y = 2x + 3 \\end{cases}$$

\\ $y = 3 + \\ 2x$ $y = 3 + 2 \cdot \square$

Explanation:

Step1: Substitute x with 2

We know that \( x = 2 \), so we substitute \( x \) in the expression \( y = 3 + 2x \) with 2. So the box should be filled with 2 because we are replacing \( x \) with its value, which is 2.

Answer:

2
