how do u solve these problems?:

30/x=7+ 18/2x

3m+1/4 = 2- 3-2m/3
 

 

Hi Emanuel,

With the first problem

 30/x = 7+ 18/2x the first think I noticed is that  18/2 = 9 so you can rewrite the expression  30/x = 7+ 9/x

Now I would multiply both side by x. This will eliminate the fractions.

x( 30/x) = x(7+ 9/x) is 30 = 7x + 9 Now can you solve for x?
