Numerically, if the question looks like this:--(3a + 7b) - 8a - 4b + 2Then the answer is this:--3a - 7b - 8a - 4b + 2= -11a -11b + 2
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
a + a + a - 2a = 3a - 2a = a

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
a + 3a + 5a = 180 9a =180 a = 20
2a + 3a + 4 = 5a + 4
a + a + a - 2a = 3a - 2a = a
1
3a - 2b
