|8x-4|+4=15?

Question

|8x-4|+4=15

Answer 1

→ |8x-4| = 11
→ 8x-4 = 11 OR 8x-4 = -11

Solve away...

Answer 2

|8x-4| = 15-4
|8x-4| = 11
=> 8x-4 = +-11
coz modulus is always a positive number, so |-11| will be equal to |11| = 11
=> 8x-4 = 11 or 8x - 4 = -11
=> x = 15/8 or x = -7/8

Answer 3

Because the order of operation requires us to remove the parenths 1st in an equation , negative 4 added to positive 4 gives us zero so :

| 8X - 4 | +4 = 15

8x = 15

the next order of operation requires us to isolate the variable by division :

8x = 15

8x / 8 = 15 / 8

x = 15 / 8

Answer 4

First: subtract "4" from both sides....

|8x - 4| + 4 - 4 = 15 - 4

|8x - 4| = 11

Sec: when a problem has the absolute value sign > you have two solutions...

a. |8x - 4| = 11

*Eliminate the absolute value sign - rewrite the expression...

8x - 4 = 11

*Add 4 with both sides...

8x - 4 + 4 = 11 + 4
8x = 15

*Isolate "x" on one side - divide both terms by "8"...

8x/8 = 15/8
x = 15/8

b. |8x - 4| = - 11

*Eliminate the absolute value sign - rewrite the expression...

8x - 4 = - 11

*Add 4 with both sides...

8x - 4 + 4 = - 11 + 4
8x = - 7

*Isolate "x" on one side - divide both terms by "8"...

8x/8 = -7/8
x = -7/8

Solutions: 15/8 and -7/8

Answer 5

|8x-4| = 11

2 solutions if x>0 8x-4 =11 x =15/8

if x<0 the absolute value of 8x = -7 x = -8/7

Answer 6

|8x-4|+4=15

the -4 & +4 cross each other out...

8x=15

x=1 7/8 OR 15 over 8 (15/8)

Answer 7

Simplify by combining like words on the two section. - 4- 15 + 50= 31 on the left. one hundred ninety + 12 = 202 and -4x -x = -5x on the marvelous. So, 31 + 8x = 202 - 5x Subtract 31 from the two aspects------8x = 171 - 5x upload 5x to the two aspects --------13x=171 Divide the two aspects by 13---------x = 13.153+ How did human beings arise with the thought 171 divided by 13 is fifty seven?? definitely the only reason I spoke back grew to become into to tell you which you got one answer that grew to become into very disappointing to me.........Punch it into your calculator............that particular is in for a impolite awakening while college days come to an end.

Answer 8

What's your question?

Here is a worked out example:
|6x - 3| + 2 = 29

Subtract 2 from each side, you should get
|6x - 3| = 27

Remove the absolute signs, you should two equations:
(A) 6x - 3 = 27
(B) 6x - 3 = -27

Solve (A) like this.
Add 3 to each side
6x = 39

Divide each side by 6
x = 39 / 6 = 6.5

Solve (B) like this
Add 3 to each side
6x = -27 + 3 = -24

Divide each side by 6
x = -24/ 6 = -4

So the answer is
x = 6.5 or -4

Answer 9

Use the order of operations. P.EM.D.A.S.

P-parenthesis
