: please help me with these problems
2n+5*n=77
5+1/3n=-2
9-1/4n=6
1/8n+20=32
25-1/5n+18 This question is from textbook algebra

2n+5n=77 becomes 7n=77, which reduces to n=11 after dividing both sides by 7.
becomes 15+3n=6 after multiplying both sides by 3. Subtract 15 from sides to get 3n=-9, and divide both sides by 3 to get n=-3.
becomes 36-n=24 after multiplying both sides by 4. Subtract 36 from both sides to get -n=-12, which reduces to n=12.
becomes n+160=256 after multiplying both sides by 8. Subtracting 160 from sides gives us n=96.
You probably have a typo in the last equation, but you can use the same process as I've used here to solve it once you determine where the typo is.
