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:
$$5 x = 19$$
Divide both parts of the equation by 5
We get the answer: x = 19/5
12*x-7*x+17 = 36
Looking for similar summands in the left part:
17 + 5*x = 36
Move free summands (without x)
from left part to right part, we given:
$$5 x = 19$$
Divide both parts of the equation by 5
x = 19 / (5)
We get the answer: x = 19/5
