\frac{1}{2}\left(\frac{1}{2}\times \frac{1}{2}x+\frac{1}{2}\left(-3\right)-3\right)-3=0
Use the distributive property to multiply \frac{1}{2} by \frac{1}{2}x-3.
\frac{1}{2}\left(\frac{1\times 1}{2\times 2}x+\frac{1}{2}\left(-3\right)-3\right)-3=0
Multiply \frac{1}{2} times \frac{1}{2} by multiplying numerator times numerator and denominator times denominator.
\frac{1}{2}\left(\frac{1}{4}x+\frac{1}{2}\left(-3\right)-3\right)-3=0
Do the multiplications in the fraction \frac{1\times 1}{2\times 2}.
\frac{1}{2}\left(\frac{1}{4}x+\frac{-3}{2}-3\right)-3=0
Multiply \frac{1}{2} and -3 to get \frac{-3}{2}.
\frac{1}{2}\left(\frac{1}{4}x-\frac{3}{2}-3\right)-3=0
Fraction \frac{-3}{2} can be rewritten as -\frac{3}{2} by extracting the negative sign.
\frac{1}{2}\left(\frac{1}{4}x-\frac{3}{2}-\frac{6}{2}\right)-3=0
Convert 3 to fraction \frac{6}{2}.
\frac{1}{2}\left(\frac{1}{4}x+\frac{-3-6}{2}\right)-3=0
Since -\frac{3}{2} and \frac{6}{2} have the same denominator, subtract them by subtracting their numerators.
\frac{1}{2}\left(\frac{1}{4}x-\frac{9}{2}\right)-3=0
Subtract 6 from -3 to get -9.
\frac{1}{2}\times \frac{1}{4}x+\frac{1}{2}\left(-\frac{9}{2}\right)-3=0
Use the distributive property to multiply \frac{1}{2} by \frac{1}{4}x-\frac{9}{2}.
\frac{1\times 1}{2\times 4}x+\frac{1}{2}\left(-\frac{9}{2}\right)-3=0
Multiply \frac{1}{2} times \frac{1}{4} by multiplying numerator times numerator and denominator times denominator.
\frac{1}{8}x+\frac{1}{2}\left(-\frac{9}{2}\right)-3=0
Do the multiplications in the fraction \frac{1\times 1}{2\times 4}.
\frac{1}{8}x+\frac{1\left(-9\right)}{2\times 2}-3=0
Multiply \frac{1}{2} times -\frac{9}{2} by multiplying numerator times numerator and denominator times denominator.
\frac{1}{8}x+\frac{-9}{4}-3=0
Do the multiplications in the fraction \frac{1\left(-9\right)}{2\times 2}.
\frac{1}{8}x-\frac{9}{4}-3=0
Fraction \frac{-9}{4} can be rewritten as -\frac{9}{4} by extracting the negative sign.
\frac{1}{8}x-\frac{9}{4}-\frac{12}{4}=0
Convert 3 to fraction \frac{12}{4}.
\frac{1}{8}x+\frac{-9-12}{4}=0
Since -\frac{9}{4} and \frac{12}{4} have the same denominator, subtract them by subtracting their numerators.
\frac{1}{8}x-\frac{21}{4}=0
Subtract 12 from -9 to get -21.
\frac{1}{8}x=\frac{21}{4}
Add \frac{21}{4} to both sides. Anything plus zero gives itself.
x=\frac{21}{4}\times 8
Multiply both sides by 8, the reciprocal of \frac{1}{8}.
x=\frac{21\times 8}{4}
Express \frac{21}{4}\times 8 as a single fraction.
x=\frac{168}{4}
Multiply 21 and 8 to get 168.
x=42
Divide 168 by 4 to get 42.
