To solve the equation \( 2 + 3.3x - 1.7 = 5.25 \), first simplify the left side:
\[ 2 - 1.7 = 0.3 \]
Now the equation can be rewritten as:
\[ 0.3 + 3.3x = 5.25 \]
Next, subtract \( 0.3 \) from both sides:
\[ 3.3x = 5.25 - 0.3 \]
Calculating the right side gives:
\[ 5.25 - 0.3 = 4.95 \]
So the equation becomes:
\[ 3.3x = 4.95 \]
Now, divide both sides by \( 3.3 \):
\[ x = \frac{4.95}{3.3} \]
Calculating the division:
\[ x \approx 1.5 \]
Thus, the solution is:
\[ x \approx 1.5 \]
