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:
$$- \frac{x}{2} = -2$$
Divide both parts of the equation by -1/2
We get the answer: x = 4
(7/2)*x+(12-4*x) = 10
Expand brackets in the left part
7/2x+12-4*x = 10
Looking for similar summands in the left part:
12 - x/2 = 10
Move free summands (without x)
from left part to right part, we given:
$$- \frac{x}{2} = -2$$
Divide both parts of the equation by -1/2
x = -2 / (-1/2)
We get the answer: x = 4
