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:
$$4 x = 76$$
Divide both parts of the equation by 4
We get the answer: x = 19
5+4*x-17 = 64
Looking for similar summands in the left part:
-12 + 4*x = 64
Move free summands (without x)
from left part to right part, we given:
$$4 x = 76$$
Divide both parts of the equation by 4
x = 76 / (4)
We get the answer: x = 19
