The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 4 x = -28$$
Divide both parts of the equation by -4
We get the answer: x = 7
-4*x+9 = -19
Move free summands (without x)
from left part to right part, we given:
$$- 4 x = -28$$
Divide both parts of the equation by -4
x = -28 / (-4)
We get the answer: x = 7
