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:
$$- \frac{x}{2} = -4$$
Divide both parts of the equation by -1/2
We get the answer: x = 8
70-(2*x+4)/4 = 65
Expand brackets in the left part
70-2*x/4-4/4 = 65
Looking for similar summands in the left part:
69 - x/2 = 65
Move free summands (without x)
from left part to right part, we given:
$$- \frac{x}{2} = -4$$
Divide both parts of the equation by -1/2
x = -4 / (-1/2)
We get the answer: x = 8
