8x-3x-5=2\left(4x-1\right)
To find the opposite of 3x+5, find the opposite of each term.
5x-5=2\left(4x-1\right)
Combine 8x and -3x to get 5x.
5x-5=8x-2
Use the distributive property to multiply 2 by 4x-1.
5x-5-8x=-2
Subtract 8x from both sides.
-3x-5=-2
Combine 5x and -8x to get -3x.
-3x=-2+5
Add 5 to both sides.
-3x=3
Add -2 and 5 to get 3.
x=\frac{3}{-3}
Divide both sides by -3.
x=-1
Divide 3 by -3 to get -1.
