So to solve this question the first step should be to make 7 equal to 42. To do this multiply 7 by 6, likewise with x-4. The new equation should be 42/6x-24 = 42/12. We now can just get rid of the numerators (top number) to get 6x-24=12. The next step is to add 24 to both sides which would leave you with 6x=36. Divide by 6 and the answer should be x=6
