Answer:

Step-by-step explanation:

4b - 5 = 19

4b = 24

b = 6

4b - 5 = -19

4b = -14

b = -14/4 = -7/2

Answer: x = 6, x = -7/2, or -3.5

Step-by-step explanation:

First, split the problem in one positive and one negative

|4b-5|=19

4b - 5 = 19

-(4b-5)=19

Second, solve

4b - 5 = 19

-(4b-5)=19

Finally, simplify

4b-5=19

4b - 5 (+5) = 19 (+5)

4b = 24

4b/4 = 24/4

b = 6

For b = -7/2:

-(4x-5)=19

-4x + 5 = 19

-4x + 5 (-5) = 19 (-5)

-4x = 14

-4x/-4 = 14/-4

x = -7/2

For b = -3.5

-7/2 just simplifies into 3.5
