The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without x)
from left part to right part, we given:
$$5 x = 2 x + 2$$
Move the summands with the unknown x
from the right part to the left part:
$$3 x = 2$$
Divide both parts of the equation by 3
We get the answer: x = 2/3
5*(x-1) = 2*x-3
Expand brackets in the left part
5*x-5*1 = 2*x-3
Move free summands (without x)
from left part to right part, we given:
$$5 x = 2 x + 2$$
Move the summands with the unknown x
from the right part to the left part:
$$3 x = 2$$
Divide both parts of the equation by 3
x = 2 / (3)
We get the answer: x = 2/3
