To evaluate the expression on the right side of the equation:
Starting with the right side: \[ 2(3) + 19 \]
Calculating \( 2(3) \): \[ 2 \times 3 = 6 \]
Now adding 19: \[ 6 + 19 = 25 \]
So, the right side evaluates to: \[ 25 \]
Now we can write the full evaluation: \[ 25 = 25 \]
This confirms that the both sides of the equation are equal when \( x = 3 \).
