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:
$$- 10 x = -23$$
Divide both parts of the equation by -10
We get the answer: x = 23/10
8-5*(2*x-3) = 0
Expand brackets in the left part
8-5*2*x+5*3 = 0
Looking for similar summands in the left part:
23 - 10*x = 0
Move free summands (without x)
from left part to right part, we given:
$$- 10 x = -23$$
Divide both parts of the equation by -10
x = -23 / (-10)
We get the answer: x = 23/10
