The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$2 x = 7$$
Divide both parts of the equation by 2
We get the answer: x = 7/2
2*x-3 = 4
Move free summands (without x)
from left part to right part, we given:
$$2 x = 7$$
Divide both parts of the equation by 2
x = 7 / (2)
We get the answer: x = 7/2
