The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$7 x = 5 x - 10$$
Move the summands with the unknown x
from the right part to the left part:
$$2 x = -10$$
Divide both parts of the equation by 2
We get the answer: x = -5
7*x+1 = 5*x-9
Move free summands (without x)
from left part to right part, we given:
$$7 x = 5 x - 10$$
Move the summands with the unknown x
from the right part to the left part:
$$2 x = -10$$
Divide both parts of the equation by 2
x = -10 / (2)
We get the answer: x = -5
