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:
Divide both parts of the equation by 7
We get the answer: x = -2
14*x+10-7*x = -4
Looking for similar summands in the left part:
10 + 7*x = -4
Move free summands (without x)
from left part to right part, we given:
Divide both parts of the equation by 7
x = -14 / (7)
We get the answer: x = -2
