To solve the expression \(*x = 2 \times x + 3\) given that \(x = -5\), simply substitute \(x = -5\) into the expression and calculate.

\[
*x* = 2 \times (-5) + 3
\]

Let's solve this step by step:

1. Multiply \(2\) by \(-5\):
   \[
   2 \times (-5) = -10
   \]

2. Add \(3\) to \(-10\):
   \[
   -10 + 3 = -7
   \]

So, \(*x* = -7\) when \(x = -5\).
