the question is not clear. But as i understand, this is a linear equation so we can solve it in a simpl way.
here is the solution.
2+4+6x4x=9/7
first lets collect like terms,so we get
12x4x=9/7 then multiplying 4x by 12, we have 48x=9/7
finally dividing both sides by 48, we obtain x=9/7x48 =9/336 =3/112.
therefore, the solution is 3/112.
