It is: 7b+4b-1b = 10b when simplified
6a+7b. This cannot be simplified anymore unless you know a or b.
If b = 5, 7b = 35
If you mean 7b-2 = -51 then the value of b is -7
-58
The given expression can be simplified to: 3b-a
Unless you know the value for b, then you can't, so it would be at its most simplified form.
It is: 7b+10 simplified
It is: 7b+4b-1b = 10b when simplified
6a+7b. This cannot be simplified anymore unless you know a or b.
If b = 5, 7b = 35
7b + 15= -34 First, 7b + 15 - 15 = -34 - 15 So, 7b = -49 Then, 7b/7 = -49/7 And finally, b = -7 So b = -7
-7 7b + 15 = (-34) 7b = (-34) - 15 7b =(-49) b = (-49) / 7 b= (-7)
If you mean: -3*(-2b-3)+7b then it is an algebraic expression that can be simplified to 6b+9+7b = 13b+9
If you mean 7b-2 = -51 then the value of b is -7
If: 6b+21 = 7b-21 Then: 6b-7b = -21-21 And: -b = -42 So: b = 42
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
