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:
$$2 x = 3$$
Divide both parts of the equation by 2
We get the answer: x = 3/2
4*x+(7-2*x) = 10
Expand brackets in the left part
4*x+7-2*x = 10
Looking for similar summands in the left part:
7 + 2*x = 10
Move free summands (without x)
from left part to right part, we given:
$$2 x = 3$$
Divide both parts of the equation by 2
x = 3 / (2)
We get the answer: x = 3/2
