The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$9 x = 6 x + 26$$
Move the summands with the unknown x
from the right part to the left part:
$$3 x = 26$$
Divide both parts of the equation by 3
We get the answer: x = 26/3
9*x-7 = 6*x+19
Move free summands (without x)
from left part to right part, we given:
$$9 x = 6 x + 26$$
Move the summands with the unknown x
from the right part to the left part:
$$3 x = 26$$
Divide both parts of the equation by 3
x = 26 / (3)
We get the answer: x = 26/3
