2b + 3 b = 12 .
27 since the beginning is 2 x 12, which equals 24, and then you have to add the extra 3.
-b+5b-2b=2b
8b + 11 - 3b = 2b + 2 5b + 11 = 2b + 2 5b - 2b = 2 - 11 3b = -9 b = -3
Taking it step by step: 2b - b - 10 = -13 b - 10 = -13 b = -13 + 10 b = - 3
If: a = 2b+c Then: a-c = 2b And: b = (a-c)/2
3a + 2b = c (find a in terms of b and c)3a +2b -2b = c - 2b3a = c - 2b3a/3 = (c - 2b)/3a = (c - 2b)/3In order to find the value of a, you can give any values to b, and c (except a zero value).
2b=6squared, and 6x6=36
To simplify the expression (3(a + b) + 2b(a + b)), we first factor out ((a + b)): [ = (a + b)(3 + 2b) ] This shows that the expression can be rewritten as the product of ((a + b)) and ((3 + 2b)).
To evaluate the variable expression 3a + 2b, you need specific values for the variables a and b. Once you have those values, you substitute them into the expression and perform the arithmetic operations. For example, if a = 4 and b = 5, then 3(4) + 2(5) = 12 + 10 = 22. This gives you the final value of the expression.
To solve the equation (3(2b - 3)^2 = 36), first divide both sides by 3, giving ((2b - 3)^2 = 12). Taking the square root of both sides yields (2b - 3 = \pm \sqrt{12}), which simplifies to (2b - 3 = \pm 2\sqrt{3}). Solving for (b), we find (b = \frac{3 \pm 2\sqrt{3}}{2}). Thus, the values of (b) that satisfy the equation are (b = \frac{3 + 2\sqrt{3}}{2}) and (b = \frac{3 - 2\sqrt{3}}{2}).
6 is the average of 2a and a - 2b so 12 = 2a + a - 2b = 3a - 2b3 is the average of 2a - b and 4a + 3b so 6 = 2a - b + 4a + 3b = 6a + 2bAdding the two equations gives: 18 = 9a so that a = 2Substituting for a in the first gives 12 = 6 - 2b so that b = -36 is the average of 2a and a - 2b so 12 = 2a + a - 2b = 3a - 2b3 is the average of 2a - b and 4a + 3b so 6 = 2a - b + 4a + 3b = 6a + 2bAdding the two equations gives: 18 = 9a so that a = 2Substituting for a in the first gives 12 = 6 - 2b so that b = -36 is the average of 2a and a - 2b so 12 = 2a + a - 2b = 3a - 2b3 is the average of 2a - b and 4a + 3b so 6 = 2a - b + 4a + 3b = 6a + 2bAdding the two equations gives: 18 = 9a so that a = 2Substituting for a in the first gives 12 = 6 - 2b so that b = -36 is the average of 2a and a - 2b so 12 = 2a + a - 2b = 3a - 2b3 is the average of 2a - b and 4a + 3b so 6 = 2a - b + 4a + 3b = 6a + 2bAdding the two equations gives: 18 = 9a so that a = 2Substituting for a in the first gives 12 = 6 - 2b so that b = -3
It is an equation and the value of b is 3

3b+4 = b+12 3b-b = 12-4 2b = 8 b = 4
4/b-3 + 3/b = -2b/b-3 b = 1 or b = -4.5
3+2b+6 .... is this the question... i think the question will be 3+2b=6 b=1.5
What is the answers to -7 ( a + b - 5 ) + 8 ( -3a +2b ) + b ( 7 + 3 )
It is (B + b)/3.
