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:
$$2 x = 160$$
Divide both parts of the equation by 2
We get the answer: x = 80
(x+15)+(x+5) = 180
Expand brackets in the left part
x+15+x+5 = 180
Looking for similar summands in the left part:
20 + 2*x = 180
Move free summands (without x)
from left part to right part, we given:
$$2 x = 160$$
Divide both parts of the equation by 2
x = 160 / (2)
We get the answer: x = 80
