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:
$$- 4 x = -10$$
Divide both parts of the equation by -4
We get the answer: x = 5/2
x-5*(x-3) = 5
Expand brackets in the left part
x-5*x+5*3 = 5
Looking for similar summands in the left part:
15 - 4*x = 5
Move free summands (without x)
from left part to right part, we given:
$$- 4 x = -10$$
Divide both parts of the equation by -4
x = -10 / (-4)
We get the answer: x = 5/2
