n+7/2n+1=18n/11n-2
We move all terms to the left:
n+7/2n+1-(18n/11n-2)=0
Domain of the equation: 2n!=0
n!=0/2
n!=0
n∈R
Domain of the equation: 11n-2)!=0We get rid of parentheses
n∈R
n+7/2n-18n/11n+2+1=0
We calculate fractions
(-36n^2)/22n^2+n+77n/22n^2+2+1=0
We add all the numbers together, and all the variables
(-36n^2)/22n^2+n+77n/22n^2+3=0
We multiply all the terms by the denominator
(-36n^2)+n*22n^2+77n+3*22n^2=0
We add all the numbers together, and all the variables
(-36n^2)+77n+n*22n^2+3*22n^2=0
Wy multiply elements
(-36n^2)+22n^3+66n^2+77n=0
We get rid of parentheses
-36n^2+22n^3+66n^2+77n=0
