To use the distributive property to simplify the expression \((-1 + 7 + 9)3x\), we first simplify the expression inside the parentheses:

\[
-1 + 7 + 9 = 6 + 9 = 15.
\]

Now, we rewrite the original expression using this result:

\[
15 \cdot 3x.
\]

Next, we can use the distributive property to expand this:

\[
15 \cdot 3x = (15 \cdot 3)x = 45x.
\]

Thus, the equivalent variable expression is:

\[
\boxed{45x}.
\]
