9a + 3b - 11a - 4b = -2a -b
3b -1
Change the order to make it more obvious: 3a - a + 2b + 4b 2a + 6b or 2 (a + 3b).
-7+3b = 4b-8 3b-4b = -8+7 -b = -1 b = 1
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
1a+3b 2a+4b=3a +7b
9a + 3b - 11a - 4b = -2a -b
2a-3+4b-2a-b-3+5=3b-1
To simplify the expression 2a - 3 + 4b - 2a - b - 3 + 5, we first combine like terms. Combining the terms with 'a', we have 2a - 2a = 0. Combining the terms with 'b', we have 4b - b = 3b. Combining the constants, we have -3 - 3 + 5 = -1. Therefore, the simplified expression is 3b - 1.
