The solution of given equation 
<u>Step-by-step explanation:</u>
Given equation 1+3 x = -x +4
<em> Add 'x' on both sides , we get</em>
1 + 3 x + x = - x + x +4
1 + 4 x = 4
<em> Subtract '1' on both sides , we get</em>
<em> 1+4 x -1 = 4 -1</em>
4 x = 3
<em> Dividing '4' on both sides, we get</em>


<u><em>Final answer</em></u>:-
