(3a+7)+(a−1)

The sum is ___

Answer 1

Answer:

4a+6

Step-by-step explanation:

To find the answer to this problem, you need to combine the like terms. (3a+7)+(a-1)=(3a+a)+(7-1)=4a+6. Hope this helps!

Answer 2

The singular “a” represents 1a because you’re not subtracting either a you add it. Lets say this:
= 3a + (1)a = 4a

7 - 1 =6

Then just put the equation together, making : 4a + 6
