The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$9 x = 7 x - 8$$
Move the summands with the unknown x
from the right part to the left part:
$$2 x = -8$$
Divide both parts of the equation by 2
We get the answer: x = -4
9*x+13 = 7*x+5
Move free summands (without x)
from left part to right part, we given:
$$9 x = 7 x - 8$$
Move the summands with the unknown x
from the right part to the left part:
$$2 x = -8$$
Divide both parts of the equation by 2
x = -8 / (2)
We get the answer: x = -4
