$\huge{ \bold{ \boxed{ \text{4a + 6}}}}$

Step-by-step explanation:

$\text{ (3a + 7) + (a - 1)}$

In addition , sign of each term in the expression remains unchanged. So, Remove the unnecessary brackets.

$\text{⇢ \: 3a + 7 + a - 1}$

Combine like terms. Like terms are those which have the same base. Only coefficients of like terms can be added or subtracted.

$\text{⇢ \: 3a + a + 7 - 1}$

$\text{⇢ \boxed{ \text{4a + 6}}}$

And we're done! :D

Hope I helped!

Best regards! :D
