The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$2 x = 5 - 2 x$$
Move the summands with the unknown x
from the right part to the left part:
$$4 x = 5$$
Divide both parts of the equation by 4
We get the answer: x = 5/4
7*x-5*(x+1) = -2*x
Expand brackets in the left part
7*x-5*x-5*1 = -2*x
Looking for similar summands in the left part:
-5 + 2*x = -2*x
Move free summands (without x)
from left part to right part, we given:
$$2 x = 5 - 2 x$$
Move the summands with the unknown x
from the right part to the left part:
$$4 x = 5$$
Divide both parts of the equation by 4
x = 5 / (4)
We get the answer: x = 5/4
