The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 18 x = - 25 x - 28$$
Move the summands with the unknown x
from the right part to the left part:
$$7 x = -28$$
Divide both parts of the equation by 7
We get the answer: x = -4
16-18*x = -25*x-12
Move free summands (without x)
from left part to right part, we given:
$$- 18 x = - 25 x - 28$$
Move the summands with the unknown x
from the right part to the left part:
$$7 x = -28$$
Divide both parts of the equation by 7
x = -28 / (7)
We get the answer: x = -4
