# If y = 3x + 5, what is the value of y when x = 12?

Feb 21, 2018

$41$

#### Explanation:

$x = 12$

so

$y = 3 \cdot 12 + 5$

$= 36 + 5$

$= 41$

$y = 41$

#### Explanation:

For this equation, you plug in the value of $x$, which is $12$. So, it would look like this:

$y = 3 \left(12\right) + 5$

Then, you multiply $3$ by $12$ to get $36$, and finally, you add it to $5$. Since

$36 + 5 = 41$

the value of $y$ is $41$.
