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:
$$2 x = 14$$
Divide both parts of the equation by 2
We get the answer: x = 7
2*(x-2)-10 = 0
Expand brackets in the left part
2*x-2*2-10 = 0
Looking for similar summands in the left part:
-14 + 2*x = 0
Move free summands (without x)
from left part to right part, we given:
$$2 x = 14$$
Divide both parts of the equation by 2
x = 14 / (2)
We get the answer: x = 7
