The solution
Detail solution
Given the linear equation:
Looking for similar summands in the right part:
Move free summands (without x)
from left part to right part, we given:
$$15 x = 15$$
Divide both parts of the equation by 15
We get the answer: x = 1
15*x+10 = 5+20
Looking for similar summands in the right part:
10 + 15*x = 25
Move free summands (without x)
from left part to right part, we given:
$$15 x = 15$$
Divide both parts of the equation by 15
x = 15 / (15)
We get the answer: x = 1
