5a - 5 = 7 + 2a ( subtract 2a from both sides) 3a - 5 = 7 (add 5 to both sides) 3a = 12 ( divide both sides by 3) a = 4
4ab - 2a - 7

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).
5a - 5 = 7 + 2a ( subtract 2a from both sides) 3a - 5 = 7 (add 5 to both sides) 3a = 12 ( divide both sides by 3) a = 4
7
4ab - 2a - 7
If you mean: 4a-3 = 2a+7 then the value of a works out as 5
2a - 7 = -9 2a - 7 + 7 = -9 + 7 2a = -9 +7 2a = -2 2a/2 = -2/2 a = -2/2 a= -1
The problem 3a-1 and 2a-5 is greater by 7. This is a math problem.
a=5
2a+5a=3 7a=3 a=3/7 or .4286

5 = 1 x 5, 21 = 3 x 7 3 x 5 = 15, 1 x 7 = 7, 15 - 7 = 8 so: (5x + 7)(x - 3)
2a+7 is a binomial, because it has two terms (2a and 7).
7/8 + 5/6 = 42/48 + 40/48 = 82/48 = 134/48 = 117/24
