B evaluates to 8. Here is how the formula may look:
15 = 7 + b
Now we have to isolate the b. The easiest way is to subtract the 7. Remember that what we do to one side, we must do to the other side.
15 - 7 = 7 + b - 7
It is time to simplify. On the left we know that 15 minus 7 is 8. On the right, the +7 and the -7 cancel each other out and can all be removed. That leaves b.
8 = b
What else can I help you with?
4b plus 3 equals 15 solving two step equations?
4b+3=15 4b=15-3 b=(15-3)/4 b=3
How do I solve for y the linear equations 8x-7y equals 7 and 7x equals 8y equals 8?
8x - 7y = 7 (A)7x + 8y = 8 (B)7*(A): 56x - 49y = 498*(B): 56x + 64y = 648*(B)-7*(A): (64+49)*y = 64-49=> 113y = 15=> y = 15/113
How you solve b plus 7 equals 18?
b + 7 = 18 subtract 7 from each side b + 7 - 7 = 18 - 7 b = 11 ----------------check in original equation 11 + 7 = 18 18 = 18 --------------checks
A squared plus b squared equals c squared?
This is the common form of the Pythagorean Theorem. It describes the relationship between the two legs of a right triangle and the hypotenuse.
How do you solve for x when a plus x equals b?
x=b-a
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 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
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 value of a plus b if a equals -7 and b equals 10?
3
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.
What is the value of a plus b if a equals 6 and b equals 9?
a = 6b = 9a + b = 6 + 9 = 15
What is the compound sentence of abs value ax plus b equals 15?
ax + b = 15 or ax + b = -15
How do you solve 15 plus b equals 23?
15+b = 23 Subtract 15 from both sides b = 8
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
For which equation is b equals 8 a solution?
15-b=7.
