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

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

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
