Algebra
can you please simplify it ?
1. 8h-(3h+2k) 2. 5(m=n)-(3m+2n)

Re: Algebra
1. Distribute the minus sign through: 8h - 3h - 2k. This becomes 5h - 2k.
2. 5(m=n)-(3m+2n) -- The parentheses don't make sense here. I'm going to rewrite it as 5m = n - (3m + 2n). Now:
5m + 3m + 2n = n
8m = -n
Solve for either:
n = -8m
m = -n/8

Re: Algebra
I'm thinking that toru missed the shift key in problem 2, making it 5(m+n)-(3m+2n).
5m + 5n - 3m - 2n = 2m + 3n.
I am at an age where I have forgotten more than I remember, but I still pretend to know it all.
