cross multiplication of algebra expression denominators

How do I get matlab to do the cross multiplcation and display my equation without fractions?

I would like to see the equation after cross multiplying by a and b. ( by = abk + ax )

eq = ( y/a == k+x/b )

eq = (sym)

y x

─ = k + ─

a b

syms x y a b k
eq = y/a == k+x/b

eq = 

Symple enough. :)

eq = expand(eq*a*b)

eq =
