Step-by-step explanation:

Step 1: Define

y = 2x + 12

x = 3

Step 2: Evaluate

1. Substitute in x:                                                                                                y = 2(3) + 12
2. Multiply:                                                                                                           y = 6 + 12
3. Add:                                                                                                                 y = 18

Answer 2

$\huge\text{Hey there!}$

$\large\text{If x = 3, then SUBSTITUTE it where the x value is in the equation}$

$\large\text{y = 2x + 12}\\\large\text{y = 2(3) + 12}\\\large\text{2(3) = 6}\\\large\text{y = 6 + 12}\\\large\text{6 + 12}\rightarrow\large\text{\bf 18}\\\large\text{y = \bf 18 }\large\checkmark\\\\\\\boxed{\boxed{\huge\text{Answer: \bf y = 18}}}\huge\checkmark$
