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:
$$x = 46$$
We get the answer: x = 46
20+(x-11) = 55
Expand brackets in the left part
20+x-11 = 55
Looking for similar summands in the left part:
9 + x = 55
Move free summands (without x)
from left part to right part, we given:
$$x = 46$$
We get the answer: x = 46
