-7 7b + 15 = (-34) 7b = (-34) - 15 7b =(-49) b = (-49) / 7 b= (-7)
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
It is an equation and the value of b is 3
3b -2 =7 b+4
It is: 19b+7b = 26b
-7 7b + 15 = (-34) 7b = (-34) - 15 7b =(-49) b = (-49) / 7 b= (-7)
-58
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 + (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
It is an equation and the value of b is 3
3b -2 =7 b+4
It is: 19b+7b = 26b
It is: 7b+10 simplified
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
If b = -1.5 then -4.5 -2 = -10.5 + 4, which is true.
