3a - 2b
-6(a-3b-9c)
6+7a+6b
11a+7b-(3b-2a)
It is: 4b+6
2a
It is: b+4 when simplified
3A + 9B = 3(A + 3B)
To simplify the expression (8a + 4b + 4a + 3b), first combine like terms. Add the coefficients of (a): (8a + 4a = 12a). Then, add the coefficients of (b): (4b + 3b = 7b). Thus, the simplified expression is (12a + 7b).
0.6b + 3c
3b -1
Oh, dude, you're hitting me with some math right off the bat! So, like, 3b squared minus 3b is basically 3b times b minus 3b, which equals 3b squared minus 3b. It's like the math version of a magic trick - it looks complicated, but it's just simplifying terms.
5b + 11 - 2b = 3b + 11
