solve 2|x+1|=8

Answer 1

x=3 and -5

Explanation:

to start with when you work with equations there will be two answers, no solution set or the answer will be 0. in this case there are two answers.

2/x+1/=8(first you remove all the things that are extra to the equation)

2 2

/x+1/=4 in this case it has two answers because 4 is greater than 0.

so you remove the bracket.

x+1=4 or x+1=-4

x=4-1 x=-4-1

x=3 x=-5

Answer 2

x = 3 x = -5

Explanation:

2|x+1|=8

Divide each side by 2

2/2|x+1|=8/2

|x+1| = 4

There are two solutions to an absolute value, one positive and one negative

x+1 = 4 x+1 = -4

Subtract 1 from each side

x+1 -1 = 4-1 x+1-1 = -4-1

x = 3 x = -5
