9n+2n-1-36=3\left(2n+7\right)
Multiply both sides of the equation by 9, the least common multiple of 9,3.
11n-1-36=3\left(2n+7\right)
Combine 9n and 2n to get 11n.
11n-37=3\left(2n+7\right)
Subtract 36 from -1 to get -37.
11n-37=6n+21
Use the distributive property to multiply 3 by 2n+7.
11n-37-6n=21
Subtract 6n from both sides.
5n-37=21
Combine 11n and -6n to get 5n.
5n=21+37
Add 37 to both sides.
5n=58
Add 21 and 37 to get 58.
n=\frac{58}{5}
Divide both sides by 5.
