The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Looking for similar summands in the right part:
Move the summands with the other variables
from left part to right part, we given:
$$16 x = 5 k + 15 x$$
Move the summands with the unknown x
from the right part to the left part:
$$x = 5 k$$
We get the answer: x = 5*k
16*x+5*k = 15*x+10*k
Looking for similar summands in the left part:
5*k + 16*x = 15*x+10*k
Looking for similar summands in the right part:
5*k + 16*x = 10*k + 15*x
Move the summands with the other variables
from left part to right part, we given:
$$16 x = 5 k + 15 x$$
Move the summands with the unknown x
from the right part to the left part:
$$x = 5 k$$
We get the answer: x = 5*k
