The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$7 x = 5 x - 19$$
Move the summands with the unknown x
from the right part to the left part:
$$2 x = -19$$
Divide both parts of the equation by 2
We get the answer: x = -19/2
7*x+3 = 5*x-16
Move free summands (without x)
from left part to right part, we given:
$$7 x = 5 x - 19$$
Move the summands with the unknown x
from the right part to the left part:
$$2 x = -19$$
Divide both parts of the equation by 2
x = -19 / (2)
We get the answer: x = -19/2
