The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$11 x = 4 x + 28$$
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
11*x-9 = 4*x+19
Move free summands (without x)
from left part to right part, we given:
$$11 x = 4 x + 28$$
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
