Answer 1

$\huge\tt\colorbox{gray}{Answer}$

$3a + \frac{2}{5} = 5$

$3a = 5 - \frac{2}{5}$

$3a = \frac{25 - 2}{5}$

$3a = \frac{23}{5}$

$a = \frac{23}{5 \times 3}$

$a = \frac{23}{15}$

Answer 2

Answer:

a = 23/15

Step-by-step explanation:

We subtract 2/5 from both sides to get:

3a = 4 3/5

We can simplify the RHS (Right Hand side) to get:

3a = 23/5

We divide each side by 3 to get our answer:

a = 23/15
