Answer:
A B D
Step-by-step explanation:
A=4=10-n
4 ? 10-6
10-6=4
therefore 6 is a solution
choice B=3=n/2
3=6/2
3=3
yes n = 6 is a solution
choice c= 12=n+7
12=6+7
12=13
no N =6 is not a solution
Choice d
8n=48
8*6=48
48=48
yes n= 6 is a solution
Choice e
5+n=8
5+6 ? 8
11 = /8
no N= not a solution of 6
