3k-60-\sqrt{3}k=40
Subtract \sqrt{3}k from both sides.
3k-\sqrt{3}k=40+60
Add 60 to both sides.
3k-\sqrt{3}k=100
Add 40 and 60 to get 100.
\left(3-\sqrt{3}\right)k=100
Combine all terms containing k.
\frac{\left(3-\sqrt{3}\right)k}{3-\sqrt{3}}=\frac{100}{3-\sqrt{3}}
Divide both sides by 3-\sqrt{3}.
k=\frac{100}{3-\sqrt{3}}
Dividing by 3-\sqrt{3} undoes the multiplication by 3-\sqrt{3}.
k=\frac{50\sqrt{3}}{3}+50
Divide 100 by 3-\sqrt{3}.
