Answer:
n=7
Step-by-step explanation:
1/10n-3/10=4/10
1/10n-3/10+310=4/10+310
1/10n=7/10
10x1/10n=7x10/10
n=7
I hope this helps!
n=7
1/10n-3/10=4/10
(add the -3/10 to the other side)
1/10n=7/10
(Than divide)
You get n=7
1/10n-3/10=4/10
(add the -3/10 to the other side)
1/10n=7/10
(Than divide)
You get n=7
