If you mean: 2(a+3)-12 then it can be simplified to 2a-6
Since the question is 3(2a), then just write it out. 3(2a) is 2a+2a+2a or 6a.
The multiplicative inverse of -2a is 1/(-2a) = -1/2a
2a+2a-7b+7b =4a
a-^2a-b^-a-b
The answer is 4a^2.
a + a + a - 2a = 3a - 2a = a
2a2
2a + 2b = c subtract 2a from both sides 2a - 2a + 2b = c - 2a 2b = c - 2a divide both sides by 2 (2/2)b = (c - 2a)/2 b = (c - 2a)/2 --------------------

3a-2a = 1
312 into a fraction = 312/1
