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:
$$2 x = 15 y - 1$$
Divide both parts of the equation by 2
We get the answer: x = -1/2 + 15*y/2
2*x-15*y = -1
Looking for similar summands in the left part:
-15*y + 2*x = -1
Move the summands with the other variables
from left part to right part, we given:
$$2 x = 15 y - 1$$
Divide both parts of the equation by 2
x = -1 + 15*y / (2)
We get the answer: x = -1/2 + 15*y/2
