The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$x = 44 - 2 x$$
Move the summands with the unknown x
from the right part to the left part:
$$3 x = 44$$
Divide both parts of the equation by 3
We get the answer: x = 44/3
x+4 = 48-2*x
Move free summands (without x)
from left part to right part, we given:
$$x = 44 - 2 x$$
Move the summands with the unknown x
from the right part to the left part:
$$3 x = 44$$
Divide both parts of the equation by 3
x = 44 / (3)
We get the answer: x = 44/3
