\frac{3}{2}-\frac{4}{2}-6x=-3x+\frac{12}{13}
Convert 2 to fraction \frac{4}{2}.
\frac{3-4}{2}-6x=-3x+\frac{12}{13}
Since \frac{3}{2} and \frac{4}{2} have the same denominator, subtract them by subtracting their numerators.
-\frac{1}{2}-6x=-3x+\frac{12}{13}
Subtract 4 from 3 to get -1.
-\frac{1}{2}-6x+3x=\frac{12}{13}
Add 3x to both sides.
-\frac{1}{2}-3x=\frac{12}{13}
Combine -6x and 3x to get -3x.
-3x=\frac{12}{13}+\frac{1}{2}
Add \frac{1}{2} to both sides.
-3x=\frac{24}{26}+\frac{13}{26}
Least common multiple of 13 and 2 is 26. Convert \frac{12}{13} and \frac{1}{2} to fractions with denominator 26.
-3x=\frac{24+13}{26}
Since \frac{24}{26} and \frac{13}{26} have the same denominator, add them by adding their numerators.
-3x=\frac{37}{26}
Add 24 and 13 to get 37.
x=\frac{\frac{37}{26}}{-3}
Divide both sides by -3.
x=\frac{37}{26\left(-3\right)}
Express \frac{\frac{37}{26}}{-3} as a single fraction.
x=\frac{37}{-78}
Multiply 26 and -3 to get -78.
x=-\frac{37}{78}
Fraction \frac{37}{-78} can be rewritten as -\frac{37}{78} by extracting the negative sign.
