2 - 3b = 7b + 12
Let us introduce equal terms (3b - 12 in this specific case) on each side (left and right) of the equal sign, so that the 'b' term is all alone on one side of the equal sign.
2 - 3b + (3 b - 12) = 7b + 12 + (3 b - 12)
-10 = 10b
b = -1

What is 7b-12 plus 2b plus 3 equals 18?
It is an equation and the value of b is 3
What does b equal in -7b equals 84?
-12
What is the answer to 2a plus 7b equals -1 3a - 7b equals -5?
2a + 7b = -13a - 7b = -5The system of equations can be solved by elimination:2a + 3a = -65a = -6a = -6/5substitute the value of a in any of the two original equations to find the value of b:2(-6/5) + 7b = -1-12/5 + 1 = -7b-7/5 = -7bb= 1/5
What is the answer to 7 b plus 15 equals -34?
-7 7b + 15 = (-34) 7b = (-34) - 15 7b =(-49) b = (-49) / 7 b= (-7)
3b - 2 equals 7b plus 4?
3b -2 =7 b+4
What is 7b-12 plus 2b plus 3 equals 18?
It is an equation and the value of b is 3
What is the answer to -7b plus equals -51?
-58
6a plus 7b - 4a - 8b equals?
6a + (7b - 4a - 8b) = (6a - 4a) + (7b - 8b) = 2a - b
What does b equal in -7b equals 84?
-12
What is the answer to 2a plus 7b equals -1 3a - 7b equals -5?
2a + 7b = -13a - 7b = -5The system of equations can be solved by elimination:2a + 3a = -65a = -6a = -6/5substitute the value of a in any of the two original equations to find the value of b:2(-6/5) + 7b = -1-12/5 + 1 = -7b-7/5 = -7bb= 1/5
What is b if 7b plus 16 equals 5b plus 24?
7b + 16 = 5b + 247b - 5b = 24 - 162b = 8b = 4
What is 6b plus 21 equals 7b-21 equal to?
If: 6b+21 = 7b-21 Then: 6b-7b = -21-21 And: -b = -42 So: b = 42
What is the answer to 7 b plus 15 equals -34?
-7 7b + 15 = (-34) 7b = (-34) - 15 7b =(-49) b = (-49) / 7 b= (-7)
3b - 2 equals 7b plus 4?
3b -2 =7 b+4
What is b if 7b plus 15 equals -34?
7b + 15= -34 First, 7b + 15 - 15 = -34 - 15 So, 7b = -49 Then, 7b/7 = -49/7 And finally, b = -7 So b = -7
What is 19b plus 7b?
It is: 19b+7b = 26b
5b plus 2b plus 10?
It is: 7b+10 simplified
