3a + (3b - 2a) + 5b =3a + 3b - 2a + 5b =(3a - 2a) + (3b + 5b) =a + 8b
1a+3b 2a+4b=3a +7b
(6ab + 9b)/(2a + 3) = 3b(2a + 3)/(2a + 3) = 3b
11a+7b-(3b-2a)
-2a plus 3b
3a + (3b - 2a) + 5b =3a + 3b - 2a + 5b =(3a - 2a) + (3b + 5b) =a + 8b
2A plus 3B times 2A - 3B = 4A2 - 9B2; this is an example of the general formula (a + b)(a - b) = a2 - b2.
(2a + b)(a + 3b)
1a+3b 2a+4b=3a +7b
(6ab + 9b)/(2a + 3) = 3b(2a + 3)/(2a + 3) = 3b
11a+7b-(3b-2a)
add like terms: 3a -2a -5b + 6b +3b - 7b = a -3b
8b -2a
2ab - 3b2 - 3b + 2a does not have a solution, as it is not an equation.
6+7a+6b
-2a plus 3b
2a-3+4b-2a-b-3+5=3b-1
