6a + (7b - 4a - 8b) = (6a - 4a) + (7b - 8b) = 2a - b
7b + 16 = 5b + 247b - 5b = 24 - 162b = 8b = 4
If you mean 7b-2 = -51 then the value of b is -7
(9,2)
11a+7b-(3b-2a)
6a + (7b - 4a - 8b) = (6a - 4a) + (7b - 8b) = 2a - b
7b + 16 = 5b + 247b - 5b = 24 - 162b = 8b = 4
If: 6b+21 = 7b-21 Then: 6b-7b = -21-21 And: -b = -42 So: b = 42
-7 7b + 15 = (-34) 7b = (-34) - 15 7b =(-49) b = (-49) / 7 b= (-7)
It is an equation and the value of b is 3
If you mean 7b-2 = -51 then the value of b is -7
3b -2 =7 b+4
7b + 15= -34 First, 7b + 15 - 15 = -34 - 15 So, 7b = -49 Then, 7b/7 = -49/7 And finally, b = -7 So b = -7
yes.W= 7
It is: 19b+7b = 26b
It is: 7b+10 simplified
