JudyOh, dude, it's like math time! So, when you add 3a and 7a together, you get 10a. It's like combining the apples and Oranges of algebra. So, the simplified answer is just 10a. Easy peasy, lemon squeezy!
When simplifying the expression 3a + 7a, you can combine the like terms, which in this case are the terms with the variable 'a'. Adding 3a and 7a gives you 10a. Therefore, the simplified form of 3a + 7a is 10a.

What is -7a plus 3a?
-7a + 3a = -4a
Simplify a plus 3a-2 plus 3a?
a + 3a - 2 + 3a. Add the a + 3a + 3a = 7a. You can't combine the -2 & 7a so the solution is: 7a - 2.
What is 3a plus 5b plus 7a?
3a+5b+7a=
3a 4b equals 7a 4b?
Clearly, there are some signs missing. So let's try the four possibilities for the second terms: 1. + and + 3a + 4b = 7a + 4b Subtract 4b from each side: 3a = 7a Subtract 3a from each side: 0 = 4a Answer : a = 0, b indeterminate (ie can have any vaue). 2. + and - 3a + 4b = 7a - 4b Subtract 4b from each side: 3a = 7a - 8b Subtract 7a from each side: -4a = -8b or 4a = 8b Answer: a = 2b 3. - and - 3a - 4b = 7a - 4b Add 4b to each side: 3a = 7a Subtract 3a from each side: 0 = 4a Answer : a = 0, b indeterminate (ie can have any vaue). 4. - and + 3a - 4b = 7a + 4b Add 4b to each side: 3a = 7a + 8b Subtract 7a from each side: -4a = 8b or 4a = -8b Answer: a = -2b Can't do better than that with the information available.
What is 4a plus 3a?
4a + 3a = (4 + 3)a = 7a
(4a-5) plus (3a plus 6)?
It is: 7a+1 when simplified
What is -7a plus 3a?
-7a + 3a = -4a
Simplify a plus 3a-2 plus 3a?
a + 3a - 2 + 3a. Add the a + 3a + 3a = 7a. You can't combine the -2 & 7a so the solution is: 7a - 2.
What is 3a plus 5b plus 7a?

Evaluate 3 a plus 4 a 6?
3a + 4a +/- 6; take the 3a & 4a and combine them; 7a +/- 6 would be your answer as 6 cannot combine with 7a due to the variable. If 7a +/- 6 = 0, then subtract/add (respectively) the 6 depending on the operation. Therefore 7a + 6 = 0 turns to 7a = -6. Divide the 7 with the -6 to get the a alone; a = -6/7 or -0.8. Cannot be simplified.
What is 3a plus 4?
7a
What is 7a-4a?

What is 4a plus 3a?
4a + 3a = (4 + 3)a = 7a
2a plus 5a simplified?
7a
What is the answer to 4a - 5 equals 7a - 7?
4a - 5 = 7a - 7 -5 = 3a - 7 2 = 3a a = 3/2
