4.7k+11.5=-12
Swap sides so that all variable terms are on the left hand side.
4.7k=-12-11.5
Subtract 11.5 from both sides.
4.7k=-23.5
Subtract 11.5 from -12 to get -23.5.
k=\frac{-23.5}{4.7}
Divide both sides by 4.7.
k=\frac{-235}{47}
Expand \frac{-23.5}{4.7} by multiplying both numerator and the denominator by 10.
k=-5
Divide -235 by 47 to get -5.
