To simplify the expression (3a + 6b + 8a + 5b), you can combine like terms. The terms with (a) are (3a) and (8a), which add up to (11a). The terms with (b) are (6b) and (5b), which combine to (11b). Therefore, the simplified expression is (11a + 11b).
20a plus 14 will be 34a minus 8a minus 7 34a minus 8 is 26a minus 7 is 19a. The single b is 1b plus 6b which is 7b minus 2b equals 5b.
11a-3a =8a so 8a+9=-7 8a = -16 a=-2
3(7a - 5b) + 2(4a - 3b) Multiply the contents of each bracket by the number outside it: 21a - 15b + 8a - 6b Bring like terms together: 21a + 8a - 15b - 6b Combine like terms: 29a - 21b This cannot be simplified further.
Numerically, if the question looks like this:--(3a + 7b) - 8a - 4b + 2Then the answer is this:--3a - 7b - 8a - 4b + 2= -11a -11b + 2
5x - 8a + 4a - 2x + a = 3x - 3a
6b+5a-4b+3a= ? Rearrange it as 5a+3a+6b-4b = 8a+2b
20a plus 14 will be 34a minus 8a minus 7 34a minus 8 is 26a minus 7 is 19a. The single b is 1b plus 6b which is 7b minus 2b equals 5b.
-8a + 3a = (-8 + 3)a = (5)a = 5a
11a-3a =8a so 8a+9=-7 8a = -16 a=-2
3(7a - 5b) + 2(4a - 3b) Multiply the contents of each bracket by the number outside it: 21a - 15b + 8a - 6b Bring like terms together: 21a + 8a - 15b - 6b Combine like terms: 29a - 21b This cannot be simplified further.
8a+2b
Numerically, if the question looks like this:--(3a + 7b) - 8a - 4b + 2Then the answer is this:--3a - 7b - 8a - 4b + 2= -11a -11b + 2
5x - 8a + 4a - 2x + a = 3x - 3a
it could be anything. What is a? if it is 3 then you do 4x3=12+3x3=9+3=24 * * * * * It is 8a.
So we have 5a + 11 + 3a - 7 = -4 Start by combining common terms such as the 5a and 3a to give you 8a and 11 and -7 to give you 4. So now your equation is 8a + 4 = -4. Subtract 4 from both sides gives you 8a = -8. Divide -8 by 8 to give you a = -1, your solution.
2a - 4y = 3a - 8a - 5y 7a = -ya = -(y/7)
Add the equations: 4a + 4a - 5b + 5b = 7 + 17 ie 8a = 24 a = 3, so b = 1
