Answer:

3* ( n+2) = n-4

n=-5

Explanation:

Three times the sum of a number and 2 is the same as the number minus 4

3* ( n+2) = n-4

Distribute

3n +6 = n-4

Subtract n from each side.

3n-n +6 =n-n-4

2n +6 = -4

Subtract 6 from each side.

2n +6-6 = -4-6

2n = -10

Divide by 2 on each side.

2n/2 = -10/2

n = -5
