12=25-x-19-\left(-2x\right)
To find the opposite of 19-2x, find the opposite of each term.
12=25-x-19+2x
The opposite of -2x is 2x.
12=6-x+2x
Subtract 19 from 25 to get 6.
12=6+x
Combine -x and 2x to get x.
6+x=12
Swap sides so that all variable terms are on the left hand side.
x=12-6
Subtract 6 from both sides.
x=6
Subtract 6 from 12 to get 6.
