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
2 + 3A + 9A = 2 + 12AThe numerical value depends on the value of 'A'.It changes whenever 'A' changes.
a + 3a - 2 + 3a. Add the a + 3a + 3a = 7a. You can't combine the -2 & 7a so the solution is: 7a - 2.
x^3 + ax + 3a + 3x^2 = (x^3 + 3x^2) + (ax + 3a) = x^2(x + 3) + a(x + 3) = (x + 3)(x^2 + a)
If 3a+5=5a+3, then: 3a+5 - 3a = 5a+3 - 3a 5=2a+3 5 - 3=2a+3 - 3 2=2a a=1
The answer to the expression 3a + 4 depends on the value of 'a' as it is a variable. If 'a' is a specific number, you would first multiply 3 by 'a' and then add 4 to the result. For example, if 'a' is 2, the answer would be 3(2) + 4 = 6 + 4 = 10. In general, the expression simplifies to 3a + 4.
2 + 3A + 9A = 2 + 12AThe numerical value depends on the value of 'A'.It changes whenever 'A' changes.
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
12
It is 6a + 4
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+2)+2=
The solution for the value of 3a would be -3. The equation would be 6a + 3(4) = 2.
6a-3
13a - 6 + a = 5a + 3 + 3a 13a + a - 5a - 3a = 3 + 6 6a = 9 6a/6 = 9/6 a = 3/2
It can be simplified to: 3a^2 +10a+7 or factored as (3a+7)(a+1)
5a
9a^2 + 42at + 49t^2 = (3a + 7t)(3a + 7t)
