(4n-18)+(n-9)=(151-5n)
We move all terms to the left:
(4n-18)+(n-9)-((151-5n))=0
We add all the numbers together, and all the variables
(4n-18)+(n-9)-((-5n+151))=0
We get rid of parentheses
4n+n-((-5n+151))-18-9=0
We calculate terms in parentheses: -((-5n+151)), so:We add all the numbers together, and all the variables
(-5n+151)
We get rid of parentheses
-5n+151
Back to the equation:
-(-5n+151)
5n-(-5n+151)-27=0
We get rid of parentheses
5n+5n-151-27=0
We add all the numbers together, and all the variables
10n-178=0
We move all terms containing n to the left, all other terms to the right
10n=178
n=178/10
n=17+4/5
