You need to solve for a by getting it by itself. You do this by performing the same operation on both sides of the equation
3a + 2 = a -6
subtract 2 from both sides:
3a = a -8
subtract a from both sides:
2a = -8
divide both sides by 2:
a = -4

What is the answer to 2 plus 3A plus 9A?
2 + 3A + 9A = 2 + 12AThe numerical value depends on the value of 'A'.It changes whenever 'A' changes.
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 x3 plus ax plus 3a plus 3x2?
x^3 + ax + 3a + 3x^2 = (x^3 + 3x^2) + (ax + 3a) = x^2(x + 3) + a(x + 3) = (x + 3)(x^2 + a)
3a plus 5 equals 5a plus 3?
If 3a+5=5a+3, then: 3a+5 - 3a = 5a+3 - 3a 5=2a+3 5 - 3=2a+3 - 3 2=2a a=1
What is 3a plus 2b?
3a + 2b is an expression in algebra. If you make 3a + 2b equal to something then you can find the values of "a" and "b" Lets say you make 3a + 2b equal to 23 3a + 2b = 23 Now find "a" and "b" to make this equation true... 3(5) + 2(4) = 23 15 + 8 = 23 23 = 23 Correct So in this case a=5 and b=4
What is the answer to 2 plus 3A plus 9A?
2 + 3A + 9A = 2 + 12AThe numerical value depends on the value of 'A'.It changes whenever 'A' changes.
What is a plus 3a-2 plus 3a simplified?
7a minus 2, if "3a-2" means 3a minus 2. 3a plus 1 and 1-3rd in parenthesis times 3a, if "3a-2" means 3a squared. a plus 3a squared plus 3a = 1-3rd times 3a plus 3a times 3a plus 1 times 3a = 3a plus 1 and 1-3rd in parenthesis times 3a
If a equals 2 what is the value of 3a plus 6?
12
What is 3a plus 2 plus 3a plus 2?
It is 6a + 4
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.
-2(3a plus 2) plus 2?
-2(3a+2)+2=
If 6a plus 3b equals 2 and b 4 then what is the value of 3a?
The solution for the value of 3a would be -3. The equation would be 6a + 3(4) = 2.
3a plus 2 plus 3a-5?
6a-3
What is the value of a in 13a - 6 plus a equals 5a plus 3 plus 3a?
13a - 6 + a = 5a + 3 + 3a 13a + a - 5a - 3a = 3 + 6 6a = 9 6a/6 = 9/6 a = 3/2
3a(a plus 4)-2a plus 7?
It can be simplified to: 3a^2 +10a+7 or factored as (3a+7)(a+1)
What is 3a plus 2?
5a
How do you factor 9a2 plus 42at plus 49t2?
9a^2 + 42at + 49t^2 = (3a + 7t)(3a + 7t)
