Here we see that.
3-x=-4,so value of x=to We have to arrange it variable one side and another side constant
- First put - x in right hand side it's sign will change it becomes x. Now put-4 to left hand side it becomes 4
- Now solve it. Like that
- 3+4=x
- 7=x. Value of x is 7.
I thinks you understood it
