3x-\left(-1\right)-\left(-2x\right)=16
To find the opposite of -1-2x, find the opposite of each term.
3x+1-\left(-2x\right)=16
The opposite of -1 is 1.
3x+1+2x=16
The opposite of -2x is 2x.
5x+1=16
Combine 3x and 2x to get 5x.
5x=16-1
Subtract 1 from both sides.
5x=15
Subtract 1 from 16 to get 15.
x=\frac{15}{5}
Divide both sides by 5.
x=3
Divide 15 by 5 to get 3.
