Hello Hiiii8889!
Given, 2x + 4x = 1x. Here, we need to find the value of x.

The value of x will be 0.
Steps :
- Add 2x & 4x. You'll get 6x.
 - Now, bring 1x which lies on the other side of the equation to 6x.
 - Subtract 1x from 6x. Now our equation is, 5x = 0
 - On bringing 5 to the right side of the equation, we have to divide 0 by 5. The answer is 0.
 - So, we got the final answer as x = 0.
