The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without x)
from left part to right part, we given:
$$10 x = -27$$
Divide both parts of the equation by 10
We get the answer: x = -27/10
10*(x+2) = -7
Expand brackets in the left part
10*x+10*2 = -7
Move free summands (without x)
from left part to right part, we given:
$$10 x = -27$$
Divide both parts of the equation by 10
x = -27 / (10)
We get the answer: x = -27/10
