The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$7 x = 2 x + 7$$
Move the summands with the unknown x
from the right part to the left part:
$$5 x = 7$$
Divide both parts of the equation by 5
We get the answer: x = 7/5
-4+7*x = 2*x+3
Move free summands (without x)
from left part to right part, we given:
$$7 x = 2 x + 7$$
Move the summands with the unknown x
from the right part to the left part:
$$5 x = 7$$
Divide both parts of the equation by 5
x = 7 / (5)
We get the answer: x = 7/5
