11a-3a =8a
so
8a+9=-7
8a = -16
a=-2
Numerically, if the question looks like this:--(3a + 7b) - 8a - 4b + 2Then the answer is this:--3a - 7b - 8a - 4b + 2= -11a -11b + 2
To simplify the expression (3a + 6b + 8a + 5b), you can combine like terms. The terms with (a) are (3a) and (8a), which add up to (11a). The terms with (b) are (6b) and (5b), which combine to (11b). Therefore, the simplified expression is (11a + 11b).
7a minus 2, if "3a-2" means 3a minus 2. 3a plus 1 and 1-3rd in parenthesis times 3a, if "3a-2" means 3a squared. a plus 3a squared plus 3a = 1-3rd times 3a plus 3a times 3a plus 1 times 3a = 3a plus 1 and 1-3rd in parenthesis times 3a
If a + b = 6, what is the value of 3a + 3b?
Subtract 6 from each side: 3a = -14 Divide each side by 3: a = -14/3 ie = Minus four and two thirds

3a + 5b - 6a - 9b = -3a - 4b
12a + a - 3a = 10a
If a + b = 6, what is the value of 3a + 3b?
Subtract 6 from each side: 3a = -14 Divide each side by 3: a = -14/3 ie = Minus four and two thirds
7a-2b
2a + 3a + 4 = 5a + 4
a + 3a + 5a = 180 9a =180 a = 20
a + a + a - 2a = 3a - 2a = a
