k-\frac{3}{4}-6k-4=-3
Multiply both sides of the equation by 2.
-5k-\frac{3}{4}-4=-3
Combine k and -6k to get -5k.
-5k-\frac{3}{4}-\frac{16}{4}=-3
Convert 4 to fraction \frac{16}{4}.
-5k+\frac{-3-16}{4}=-3
Since -\frac{3}{4} and \frac{16}{4} have the same denominator, subtract them by subtracting their numerators.
-5k-\frac{19}{4}=-3
Subtract 16 from -3 to get -19.
-5k=-3+\frac{19}{4}
Add \frac{19}{4} to both sides.
-5k=-\frac{12}{4}+\frac{19}{4}
Convert -3 to fraction -\frac{12}{4}.
-5k=\frac{-12+19}{4}
Since -\frac{12}{4} and \frac{19}{4} have the same denominator, add them by adding their numerators.
-5k=\frac{7}{4}
Add -12 and 19 to get 7.
k=\frac{\frac{7}{4}}{-5}
Divide both sides by -5.
k=\frac{7}{4\left(-5\right)}
Express \frac{\frac{7}{4}}{-5} as a single fraction.
k=\frac{7}{-20}
Multiply 4 and -5 to get -20.
k=-\frac{7}{20}
Fraction \frac{7}{-20} can be rewritten as -\frac{7}{20} by extracting the negative sign.
