The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$28 x = 84$$
Divide both parts of the equation by 28
We get the answer: x = 3
13*x+15*x-24 = 60
Looking for similar summands in the left part:
-24 + 28*x = 60
Move free summands (without x)
from left part to right part, we given:
$$28 x = 84$$
Divide both parts of the equation by 28
x = 84 / (28)
We get the answer: x = 3
