We are given the equation $12x + d = 134$ and the value $x = 8$. We need to find the value of $d$.

1. Problem Description

We are given the equation $12x + d = 134$ and the value $x = 8$. We need to find the value of $d$.

2. Solution Steps

We are given the equation $12x + d = 134$.

We are also given that $x = 8$.

Substitute $x = 8$ into the equation:

$12(8) + d = 134$

$96 + d = 134$

Subtract 96 from both sides of the equation:

$96 + d - 96 = 134 - 96$

$d = 38$

3. Final Answer

The value of $d$ is 38.
