Question

Solve for x: |2x + 6| − 4 = 20

x = 9 and x = 11

x = −9 and x = 15

x = 9 and x = −15

No solution

Answer 1

|2x+6|-4=20
first step add 4 to both sides of the equation we get
|2x+6|-4+4=20+4
|2x+6|=20+4

Answer 2

next step
split the equation in 2...ie 1 positive and 1 negative ...like this
|2x+6|=24 then (2x+6)=24 and (2x+6)=-24

Answer 3

now we solve for x

Answer 4

2x+6=24
2x=24-6
2x=18
x=18/2
x=9

Answer 5

can u solve this one now
2x+6=-24

Answer 6

2x+6=-24 = -9

Answer 7

2x+6=-24
2x+6-6=-24-6
2x=-24-6
2x=-30
x=-30/2
x=-15

Answer 8

so its -9 and -15 ???????

Answer 9

how did you get -15

Answer 10

2x+6=24
2x=24-6
2x=18
x=18/2
x=9

and

2x+6=-24
2x+6-6=-24-6
2x=-24-6
2x=-30
x=-30/2
x=-15

Answer 11

ooh ok
