Answer:
n=4
Step-by-step explanation:
(7+1)+n=(4+7)+1
7+1+n=4+7+1 (subtract 7 from both sides)
1+n=4+1
1+n=5
n=5-1 (Subtract 1 from both sides)
n=4
Remember
if |a|=b then assume a=b and a=-b
divide boths ides by -3
|2x+6|=4
assume
2x+6=4 and 2x+6=-4
minus 6 both sides
2x=-2 and 2x=-10
divide by 2
x=-1 and x=-5
