Question

n=-4/7 and i have to prove it with the problem: 8=5(n+3)-3(2n-7)-20. Please help!

Answer 1

ok 8=5n+15-6n+21-20
hope you understand how i got that

Answer 2

Are you sure the problem is correct? Solving this equation will not give you n=-4/7

Answer 3

I think you may have read the problem wrong with the n value. I just tried proving it and got 16.574 instead of 8 like you should.

Answer 4

And i did this both ways
