By using the cross multiplication, we can determine the solutions to the equation w=2 , w=6.
By multiplying the numerator of one side by the denominator of other side and equating the resulting two products, cross multiplying can be used to solve a fractional equation when each side has a fraction with a single denominator.
Given the expression [tex]\frac{w}{2w-4} = \frac{4}{w}[/tex]
By using cross multiplication, we have
[tex]w^{2} = 4(2w-3)\\ w^{2} = 8w-12\\w^{2}-8w+12=0\\(w-2)(w-6)=0\\w=2 and w=6[/tex]
