To solve the equation \( 5a + 2 \cdot 2 = 32 \), first simplify the equation: 1. Calculate \( 2 \cdot 2 \): \[ 2 \cdot 2 = 4 \] 2. Substitute this back into the equation: \[ 5a + 4 = 32 \] 3. Now, isolate \( 5a \) by subtracting 4 from both sides: \[ 5a = 32 - 4 \] \[ 5a = 28 \] 4. Finally, divide both sides by 5 to find \( a \): \[ a = \frac{28}{5} \] \[ a = 5.6 \] So the solution is \( a = 5.6 \).

To solve the equation \( 5a + 2 \cdot 2 = 32 \), first simplify the equation:

Calculate \( 2 \cdot 2 \): \[ 2 \cdot 2 = 4 \]
Substitute this back into the equation: \[ 5a + 4 = 32 \]
Now, isolate \( 5a \) by subtracting 4 from both sides: \[ 5a = 32 - 4 \] \[ 5a = 28 \]
Finally, divide both sides by 5 to find \( a \): \[ a = \frac{28}{5} \] \[ a = 5.6 \]

So the solution is \( a = 5.6 \).
