Answer:
3* ( n+2) = n-4
n=-5
Step-by-step 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
