Let's solve for \( x \) step by step, following your provided steps and completing the arithmetic:
Starting with the equation: \[ 5(x + 2) = 2x + 19 \]
Distributing on the left side: \[ 5x + 10 = 2x + 19 \]
Next, we'll subtract \( 2x \) from both sides to isolate \( x \) terms on the left: \[ 5x + 10 - 2x = 19 \] This simplifies to: \[ 3x + 10 = 19 \]
Next, we subtract 10 from both sides to get: \[ 3x + 10 - 10 = 19 - 10 \] This simplifies to: \[ 3x = 9 \]
Now, divide both sides by 3: \[ x = \frac{9}{3} \] This results in: \[ x = 3 \]
So the solution is: \[ \boxed{3} \]
