To solve this equation, we first need to combine the terms on the left side:

[2/1x + 4/1x + 7/1x]

First, find a common denominator for all the terms. In this case, the common denominator is 1x:

[2x/1x + 4x/1x + 7/1x]

Now, combine the terms:

(2x + 4x + 7)/1x(6x + 7)/1x

Now the equation becomes:

(6x + 7)/x = 3

To solve for x, multiply both sides by x:

6x + 7 = 3x

Now, isolate x by moving 3x to the other side:

6x + 7 = 3x6x - 3x = -73x = -7

Finally, solve for x:

x = -7/3

So the solution to the equation is x = -7/3.
