2b-8=-b+7
3b-8=7 Add 'b' to both sides, eliminating the variable on the right side
3b=15 Add 8 to both sides to isolate the number on one side
b=5 divide each side to eliminate the coefficient on b.
The answer is b=5.

What is a and b if a plus b equals 25 and a times b equals 126?
The values of a and b are 7 and 18 or 18 and 7
What is the value of b to make the number sentence true for b plus b plus b plus 7 equals b plus 22?
b + b + b + 7 = 223b + 7 = 223b = 15b = 5
IF 2 plus 3 equals 10 7 plus 2 equals 63 6 plus 5 equals 66 8 plus 4 equals 96 THEN 9 plus 7 equals?
The answer is 144. The compound operator for (a) and (b) in each pair is a * (a+b). For 9 and 7, this is 9 x (9+7) = 9 x 16 = 144.
A square plus b equals 7 and a plus b square equals 11 what are the values of a and b?
A^2 + b = 7 A + B^2 =11 -------------- A=2 and B=34(2^2) + 3 = 7 2 + 9(3^2) = 11
What is the mathematical answer to 6b plus 14 equals -7-b?
It is: b = -3
If a plus b equals c and b plus c equals d and c plus d equals e and a equals 7 and e equals 5 what is a plus b plus c plus d plus e equal?
the answer is a

What is the mathematical answer to 6b plus 14 equals -7-b?
It is: b = -3
What is the value of a if ab plus ac equals 21 and b plus c equals 7?
To find this: You know (B+C) = 7. Therefore you know (A+A )= 21 - (B+C). Therefore 21-7 = 14. So now you know (A+A) = 14. So you divide (A+A)/2. This equals 7. Therefore A = 7.
What is the answer to 7 plus 3b equals 61?
If: 7+3b = 61 Then: b = 18
5b-4 equals 2b plus 17?
b=7
What does 9k plus 4b minus 7 minus 5k plus b equals?
That depends what the values of k and b are.
What is the answer for the formula x equals 2a b plus 7 find if a equals 3 and b equals 5?
x=2ab+7 x= 2(3)(5) +7 x=30+7 x=37
