2\left(4x-1\right)-18\left(\frac{1}{4}-\frac{x}{6}\right)=4x-8
Multiply both sides of the equation by 12, the least common multiple of 6,2,4,3.
8x-2-18\left(\frac{1}{4}-\frac{x}{6}\right)=4x-8
Use the distributive property to multiply 2 by 4x-1.
8x-2-18\left(\frac{3}{12}-\frac{2x}{12}\right)=4x-8
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 4 and 6 is 12. Multiply \frac{1}{4} times \frac{3}{3}. Multiply \frac{x}{6} times \frac{2}{2}.
8x-2-18\times \frac{3-2x}{12}=4x-8
Since \frac{3}{12} and \frac{2x}{12} have the same denominator, subtract them by subtracting their numerators.
8x-2-\frac{18\left(3-2x\right)}{12}=4x-8
Express 18\times \frac{3-2x}{12} as a single fraction.
8x-2-\frac{54-36x}{12}=4x-8
Use the distributive property to multiply 18 by 3-2x.
8x-2-\left(\frac{9}{2}-3x\right)=4x-8
Divide each term of 54-36x by 12 to get \frac{9}{2}-3x.
8x-2-\frac{9}{2}-\left(-3x\right)=4x-8
To find the opposite of \frac{9}{2}-3x, find the opposite of each term.
8x-2-\frac{9}{2}+3x=4x-8
The opposite of -3x is 3x.
8x-\frac{4}{2}-\frac{9}{2}+3x=4x-8
Convert -2 to fraction -\frac{4}{2}.
8x+\frac{-4-9}{2}+3x=4x-8
Since -\frac{4}{2} and \frac{9}{2} have the same denominator, subtract them by subtracting their numerators.
8x-\frac{13}{2}+3x=4x-8
Subtract 9 from -4 to get -13.
11x-\frac{13}{2}=4x-8
Combine 8x and 3x to get 11x.
11x-\frac{13}{2}-4x=-8
Subtract 4x from both sides.
7x-\frac{13}{2}=-8
Combine 11x and -4x to get 7x.
7x=-8+\frac{13}{2}
Add \frac{13}{2} to both sides.
7x=-\frac{16}{2}+\frac{13}{2}
Convert -8 to fraction -\frac{16}{2}.
7x=\frac{-16+13}{2}
Since -\frac{16}{2} and \frac{13}{2} have the same denominator, add them by adding their numerators.
7x=-\frac{3}{2}
Add -16 and 13 to get -3.
x=\frac{-\frac{3}{2}}{7}
Divide both sides by 7.
x=\frac{-3}{2\times 7}
Express \frac{-\frac{3}{2}}{7} as a single fraction.
x=\frac{-3}{14}
Multiply 2 and 7 to get 14.
x=-\frac{3}{14}
Fraction \frac{-3}{14} can be rewritten as -\frac{3}{14} by extracting the negative sign.
