Explanation:

Step1: Apply distributive property

$\frac{3}{5}(a) + \frac{3}{5}(5.25) = 7.35$

Step2: Calculate the constant term

$\frac{3}{5} \times 5.25 = 3.15$, so $\frac{3}{5}a + 3.15 = 7.35$

Step3: Isolate the variable term

$\frac{3}{5}a = 7.35 - 3.15$
$\frac{3}{5}a = 4.2$

Step4: Solve for $a$

$a = 4.2 \div \frac{3}{5} = 4.2 \times \frac{5}{3}$
$a = 7$

Answer:

First blank: $\frac{3}{5}$, Second blank: $\frac{3}{5}$, $a = 7$
