The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move the summands with the other variables
from left part to right part, we given:
$$4 x = 15 y + 19$$
Divide both parts of the equation by 4
We get the answer: x = 19/4 + 15*y/4
4*x-15*y = 19
Looking for similar summands in the left part:
-15*y + 4*x = 19
Move the summands with the other variables
from left part to right part, we given:
$$4 x = 15 y + 19$$
Divide both parts of the equation by 4
x = 19 + 15*y / (4)
We get the answer: x = 19/4 + 15*y/4
