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 the answer to 7 b plus 15 equals -34?
-7 7b + 15 = (-34) 7b = (-34) - 15 7b =(-49) b = (-49) / 7 b= (-7)
How do you answer 4b 15 equals 7b?
there is a sign missing -- if 4b +15 = 7b then 3b = 15 and b thus = 5 if 4b - 15 = 7b then 3b = -15 and b = -5
What is 7b-12 plus 2b plus 3 equals 18?
It is an equation and the value of b is 3
3b - 2 equals 7b plus 4?
3b -2 =7 b+4
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)
What is the answer to -7b plus equals -51?

How do you answer 4b 15 equals 7b?
there is a sign missing -- if 4b +15 = 7b then 3b = 15 and b thus = 5 if 4b - 15 = 7b then 3b = -15 and b = -5
6a plus 7b - 4a - 8b equals?
6a + (7b - 4a - 8b) = (6a - 4a) + (7b - 8b) = 2a - b
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 7b-12 plus 2b plus 3 equals 18?
It is an equation and the value of b is 3
3b - 2 equals 7b plus 4?
3b -2 =7 b+4
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 19b plus 7b?
It is: 19b+7b = 26b
5b plus 2b plus 10?
It is: 7b+10 simplified
What is the answer to 5-7b plus 6 equals -24 with steps?
5 - 7b + 6 = -24 is a linear equation in one variable. 11 - 7b = -24 Adding -11 to both sides 11 - 7b + (-11) = -24 + (-11) 11 - 7b - 11 = -24 - 11 -7b = -35 Dividing both sides by -7 -7b/(-7) = -35/(-7) b = 5
