To simplify the expression (6a + 3b - 5a - 8b), combine like terms. For the (a) terms: (6a - 5a = 1a) or just (a). For the (b) terms: (3b - 8b = -5b). Thus, the simplified expression is (a - 5b).

To simplify the expression ( A + 3B + 5A + 15B ), first combine like terms. The terms involving ( A ) are ( A ) and ( 5A ), which combine to ( 6A ). The terms involving ( B ) are ( 3B ) and ( 15B ), which combine to ( 18B ). Therefore, the simplified expression is ( 6A + 18B ).
5a 3b
(5a - 4b) + (2c - 3b - 6c) + a =5a - 4b + 2c - 3b - 6c + a =(5a + a) + (-4b - 3b) + (2c - 6c) =[ 6a - 7b - 4c ].

5a 3b
It is not an equation but an algebraic expression that can be simplified to: 12b-5a
6+7a+6b
6a+7b
The product of 5a and 3b is obtained by multiplying the coefficients (5 and 3) together and the variables (a and b) together. This results in 15ab. The product of 5a and 3b simplifies to 15ab in algebraic terms.
