2a+7 is a binomial, because it has two terms (2a and 7).
In order for the formula 3 - 2a = 7 to be solved, the value 2a must equal -4, because 3 - (- 4) = 7. Therefore, a must equal - 2.
2a + 3 - 9b - a - 7 Bring like terms together: = 2a - a - 9b + 3 - 7 Combine like terms: = a - 9b - 4
That factors to (2a - 7)(2a + 9)

2a - 7 = -9 2a - 7 + 7 = -9 + 7 2a = -9 +7 2a = -2 2a/2 = -2/2 a = -2/2 a= -1
2a+7 is a binomial, because it has two terms (2a and 7).

In order for the formula 3 - 2a = 7 to be solved, the value 2a must equal -4, because 3 - (- 4) = 7. Therefore, a must equal - 2.
2a + 3 - 9b - a - 7 Bring like terms together: = 2a - a - 9b + 3 - 7 Combine like terms: = a - 9b - 4
a = -7 - a So 2a = -7 and a = -3.5
To factorize 14a + 21, you first need to find the greatest common factor of the two terms, which in this case is 7. You can factor out 7 from both terms to get 7(2a + 3). Therefore, the factorized form of 14a + 21 is 7(2a + 3).
2a-8+4=45-5a 2a-4=45-5a 2a-4+4=45+4-5a 2a+5a=49-5a+5a 7a=49 / by 7 = A=7
That factors to (2a - 7)(2a + 9)

If you mean: 4a-3 = 2a+7 then the value of a works out as 5
