8-6x-3=5\left(2-x\right)
Use the distributive property to multiply -3 by 2x+1.
5-6x=5\left(2-x\right)
Subtract 3 from 8 to get 5.
5-6x=10-5x
Use the distributive property to multiply 5 by 2-x.
5-6x+5x=10
Add 5x to both sides.
5-x=10
Combine -6x and 5x to get -x.
-x=10-5
Subtract 5 from both sides.
-x=5
Subtract 5 from 10 to get 5.
x=-5
Multiply both sides by -1.
