3x+3=8\left(x-\frac{1}{4}\right)
Use the distributive property to multiply 3 by x+1.
3x+3=8x+8\left(-\frac{1}{4}\right)
Use the distributive property to multiply 8 by x-\frac{1}{4}.
3x+3=8x+\frac{8\left(-1\right)}{4}
Express 8\left(-\frac{1}{4}\right) as a single fraction.
3x+3=8x+\frac{-8}{4}
Multiply 8 and -1 to get -8.
3x+3=8x-2
Divide -8 by 4 to get -2.
3x+3-8x=-2
Subtract 8x from both sides.
-5x+3=-2
Combine 3x and -8x to get -5x.
-5x=-2-3
Subtract 3 from both sides.
-5x=-5
Subtract 3 from -2 to get -5.
x=\frac{-5}{-5}
Divide both sides by -5.
x=1
Divide -5 by -5 to get 1.
