The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$11 x = 7 x - 40$$
Move the summands with the unknown x
from the right part to the left part:
$$4 x = -40$$
Divide both parts of the equation by 4
We get the answer: x = -10
11*x+15 = 7*x-25
Move free summands (without x)
from left part to right part, we given:
$$11 x = 7 x - 40$$
Move the summands with the unknown x
from the right part to the left part:
$$4 x = -40$$
Divide both parts of the equation by 4
x = -40 / (4)
We get the answer: x = -10
