How do you solve the equation #(b+4)/-2=-17#?

Answer 1

#b=30#

We can undo the fact that #b+4# is divided by #-2# by multiplying both sides by #-2#.
#-2((b+4)/(-2))=(-17)(-2)#
The fractions in the left-hand side can be manipulated to show that the effect of multiplying both sides by #-2# is to have the introduced #-2# cancel with the preexisting #-2# as #1#:
#(-2)/(-2)(b+4)=(-17)(-2)#
#b+4=(-17)(-2)#
Note that #17xx2=34#. Since we have a negative multiplied by a negative, the result will be positive.
#b+4=34#
Subtract #4# from both sides of the equation:
#b+4-4=34-4#
#b=30#

Answer 2

To solve the equation (b+4)/-2=-17, you first multiply both sides by -2 to isolate (b+4). This gives you b+4 = 34. Then, you subtract 4 from both sides to isolate b, yielding b = 30.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
