(-3) squared by three - 2 (-3) squared by two = 5 (-3) - 7

Let's break this down step by step.

The given equation is:

\[
(-3)^2 \times 3 - 2 \times (-3)^2 \times 2 = 5 \times (-3) - 7
\]

### Step 1: Simplify both sides.

#### Left-hand side (LHS):

\[
(-3)^2 = 9
\]
So, substitute this into the equation:

\[
9 \times 3 - 2 \times 9 \times 2
\]

Simplify:

\[
27 - 36 = -9
\]

#### Right-hand side (RHS):

\[
5 \times (-3) - 7
\]

Simplify:

\[
-15 - 7 = -22
\]

### Step 2: Compare both sides.

The equation becomes:

\[
-9 = -22
\]

This is not true, so the equation does **not hold**.

### Final Answer:

The equation is **false**.
