-3-7n+2\left(3n-1\right)=n-11
Variable n cannot be equal to any of the values -\frac{3}{7},11 since division by zero is not defined. Multiply both sides of the equation by \left(n-11\right)\left(7n+3\right), the least common multiple of 11-n,-7n^{2}+74n+33,7n+3.
-3-7n+6n-2=n-11
Use the distributive property to multiply 2 by 3n-1.
-3-n-2=n-11
Combine -7n and 6n to get -n.
-5-n=n-11
Subtract 2 from -3 to get -5.
-5-n-n=-11
Subtract n from both sides.
-5-2n=-11
Combine -n and -n to get -2n.
-2n=-11+5
Add 5 to both sides.
-2n=-6
Add -11 and 5 to get -6.
n=\frac{-6}{-2}
Divide both sides by -2.
n=3
Divide -6 by -2 to get 3.
