3k\times 2x=\left(k+3\right)x
Variable k cannot be equal to any of the values -3,0 since division by zero is not defined. Multiply both sides of the equation by 3k\left(k+3\right), the least common multiple of k+3,3k.
6kx=\left(k+3\right)x
Multiply 3 and 2 to get 6.
6kx=kx+3x
Use the distributive property to multiply k+3 by x.
6kx-kx=3x
Subtract kx from both sides.
5kx=3x
Combine 6kx and -kx to get 5kx.
5xk=3x
The equation is in standard form.
\frac{5xk}{5x}=\frac{3x}{5x}
Divide both sides by 5x.
k=\frac{3x}{5x}
Dividing by 5x undoes the multiplication by 5x.
k=\frac{3}{5}
Divide 3x by 5x.
3k\times 2x=\left(k+3\right)x
Multiply both sides of the equation by 3k\left(k+3\right), the least common multiple of k+3,3k.
6kx=\left(k+3\right)x
Multiply 3 and 2 to get 6.
