The solution
Detail solution
Given the linear equation:
Move the summands with the unknown x
from the right part to the left part:
$$3 x = 18$$
Divide both parts of the equation by 3
We get the answer: x = 6
2*x = 18-x
Move the summands with the unknown x
from the right part to the left part:
$$3 x = 18$$
Divide both parts of the equation by 3
x = 18 / (3)
We get the answer: x = 6
