Question

Solve: d |6n+7|=8 can you guys answer me plezzzzzzzz

Answer 1

Answer: -5/2 or 1/6

Explanation:

I6n + 7I = 8

Therefore (6n + 7) = 8 or -8 because modulus means we're only getting it's absolute value, (it's positive value) meaning it could equal 8 or -8 before it's modulus'ed.

Therefore 6n + 7 = 8

or 6n + 7 = -8

Leaving us with:

6n = 1

6n = -15

So n = 1/6

or n = -5/2 (-2.5)

Answer 2

n = 1/6 n = -5/2

Explanation:

|6n+7|=8

This has two solutions, one positive and one negative

6n+7 = 8 and 6n+7 = -8

Subtract 7 from each side

6n+7-7 = 8-7 6n+7-7 =-8-7

6n =1 6n = -15

Divide by 6

6n/6 = 1/6 6n/6 = -15/6

n = 1/6 n = -5/2
