6+7a+6b
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 ).
2a + 10 + 5a - 2 = (2a + 5a) + (10 - 2) = 7a + 8

12a + 6b + 6c = 6(2a + b + c)
5a³ - 4ab + 2a³ = (5+2)a³ - 4ab = 7a³ - 4ab.
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 ).
Add them together: 2a+5a = 7a
-6(a-3b-9c)
2a + 10 + 5a - 2 = (2a + 5a) + (10 - 2) = 7a + 8
-2a plus 3b
