The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
Divide both parts of the equation by 2/3
We get the answer: x = 16
x+(7-x)/3 = 13
Expand brackets in the left part
x+7/3-x/3 = 13
Looking for similar summands in the left part:
7/3 + 2*x/3 = 13
Move free summands (without x)
from left part to right part, we given:
Divide both parts of the equation by 2/3
x = 32/3 / (2/3)
We get the answer: x = 16
