3\left(3x+5\right)-2\left(2x-5.5\right)=1
Multiply both sides of the equation by 6, the least common multiple of 2,3,6.
9x+15-2\left(2x-5.5\right)=1
Use the distributive property to multiply 3 by 3x+5.
9x+15-4x+11=1
Use the distributive property to multiply -2 by 2x-5.5.
5x+15+11=1
Combine 9x and -4x to get 5x.
5x+26=1
Add 15 and 11 to get 26.
5x=1-26
Subtract 26 from both sides.
5x=-25
Subtract 26 from 1 to get -25.
x=\frac{-25}{5}
Divide both sides by 5.
x=-5
Divide -25 by 5 to get -5.
