3-x=1+x equation
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- x = x - 2$$
Move the summands with the unknown x
from the right part to the left part:
$$- 2 x = -2$$
Divide both parts of the equation by -2
We get the answer: x = 1
3-x = 1+x
Move free summands (without x)
from left part to right part, we given:
$$- x = x - 2$$
Move the summands with the unknown x
from the right part to the left part:
$$- 2 x = -2$$
Divide both parts of the equation by -2
x = -2 / (-2)
We get the answer: x = 1
