2
It is the 2.
It is not an equation but an algebraic expression that can be simplified to: 12b-5a
To simplify the expression ( b + 5a + 7 - 3a - 2 + 2b ), first combine like terms. The ( b ) terms are ( b + 2b = 3b ), and the ( a ) terms are ( 5a - 3a = 2a ). For the constant terms, combine ( 7 - 2 = 5 ). Thus, the simplified expression is ( 3b + 2a + 5 ).
4a + 7
5
2 (or + 2)
a, whatever the value is, would be the constant.
It is the 5 in 5a+2
It is the 2.

4a + 7
14a - 4a + 5a - 3a = 12a
5
12a
It is an expression that can be simplified to: 4a+2
It is:12a
2. Although, technically, the coefficient, 5, is also a constant.
