The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$- x = - \frac{23}{12}$$
Divide both parts of the equation by -1
We get the answer: x = 23/12
2/3+5/4-x = 0
Looking for similar summands in the left part:
23/12 - x = 0
Move free summands (without x)
from left part to right part, we given:
$$- x = - \frac{23}{12}$$
Divide both parts of the equation by -1
x = -23/12 / (-1)
We get the answer: x = 23/12
