-3x-1+2x=2\left(1.5x-1\right)
To find the opposite of 3x+1, find the opposite of each term.
-x-1=2\left(1.5x-1\right)
Combine -3x and 2x to get -x.
-x-1=3x-2
Use the distributive property to multiply 2 by 1.5x-1.
-x-1-3x=-2
Subtract 3x from both sides.
-4x-1=-2
Combine -x and -3x to get -4x.
-4x=-2+1
Add 1 to both sides.
-4x=-1
Add -2 and 1 to get -1.
x=\frac{-1}{-4}
Divide both sides by -4.
x=\frac{1}{4}
Fraction \frac{-1}{-4} can be simplified to \frac{1}{4} by removing the negative sign from both the numerator and the denominator.
