8\left(x+\frac{1}{4}\right)=3\left(x-1\right)
Multiply both sides of the equation by 12, the least common multiple of 3,4.
8x+8\times \frac{1}{4}=3\left(x-1\right)
Use the distributive property to multiply 8 by x+\frac{1}{4}.
8x+\frac{8}{4}=3\left(x-1\right)
Multiply 8 and \frac{1}{4} to get \frac{8}{4}.
8x+2=3\left(x-1\right)
Divide 8 by 4 to get 2.
8x+2=3x-3
Use the distributive property to multiply 3 by x-1.
8x+2-3x=-3
Subtract 3x from both sides.
5x+2=-3
Combine 8x and -3x to get 5x.
5x=-3-2
Subtract 2 from both sides.
5x=-5
Subtract 2 from -3 to get -5.
x=\frac{-5}{5}
Divide both sides by 5.
x=-1
Divide -5 by 5 to get -1.
