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:
$$- 5 x = -200$$
Divide both parts of the equation by -5
We get the answer: x = 40
210-(10*x-5*x) = 10
Expand brackets in the left part
210-10*x+5*x = 10
Looking for similar summands in the left part:
210 - 5*x = 10
Move free summands (without x)
from left part to right part, we given:
$$- 5 x = -200$$
Divide both parts of the equation by -5
x = -200 / (-5)
We get the answer: x = 40
