The solution
Detail solution
Given the linear equation:
Looking for similar summands in the right part:
Move free summands (without x)
from left part to right part, we given:
$$x = 15$$
We get the answer: x = 15
x+43 = 4*2+50
Looking for similar summands in the right part:
43 + x = 58
Move free summands (without x)
from left part to right part, we given:
$$x = 15$$
We get the answer: x = 15
