2a + 3 - 9b - a - 7 Bring like terms together: = 2a - a - 9b + 3 - 7 Combine like terms: = a - 9b - 4
When simplified it is: 2a+8b+4
sample problem 9b + 3a - a + 6+ 2b + 4 terms would be each number or number plus a variable separated by an operation symbol (+ or -) like terms would be 9b and 2b, 3a and -a, and 6 and 4 simply add 9b + 2b (which is 11b) 3a-a (which is 2a) and 6 + 4 (which is 10) your answer would then be 11b + 2a + 10 hope that helped
3A + 9B = 3(A + 3B)
The simplified expression is -9a -9b.
There are 3 terms in the given expression of 6a+9b+15
9b + 6 - 8 = -36 9b = -38 b = 4.2222222(repeating)
They are 1, 2, 3, 4, 6, 9, 12, 18, 36,1a, 2a, 3a, 4a, 6a, 9a, 12a, 18a, 36a,1b, 2b, 3b, 4b, 6b, 9b, 12b, 18b, 36b,1a2, 2a2, 3a2, 4a2, 6a2, 9a2, 12a2, 18a2, 36a2,1ab, 2ab, 3ab, 4ab, 6ab, 9ab, 12ab, 18ab, 36ab,1b2, 2b2, 3b2, 4b2, 6b2, 9b2, 12b2, 18b2, 36b2.
10b
You would factor 3a + 9b as: 3(a+3b)
-28am + 17b
3a + 5b - 6a - 9b = -3a - 4b
