Question

|11-4b|=18
can u please help me with my homework please and thankl you

Answer 1

Answer: b=
`(29)/(4)`=
`7 (1)/(4)`=7.25

b= -
`(7)/(4) = -1 (3)/(4) = -1.7`

Explanation:

|11-4b|=18

|4b+11|=18

Use the definition of absolute value.

-4b+11= 18

-4+11= -18

Subtract 11 from both sides of the equation.

-4b= 7

-4b= -29

Divide both sides by -4.

b= -
`(7)/(4 )`

b=
`(29)/(4)`
