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:
$$2 x = 7 y + 19$$
Divide both parts of the equation by 2
We get the answer: x = 19/2 + 7*y/2
2*x-7*y = 19
Looking for similar summands in the left part:
-7*y + 2*x = 19
Move the summands with the other variables
from left part to right part, we given:
$$2 x = 7 y + 19$$
Divide both parts of the equation by 2
x = 19 + 7*y / (2)
We get the answer: x = 19/2 + 7*y/2
