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:
$$9 x = - 17 y - 3$$
Divide both parts of the equation by 9
We get the answer: x = -1/3 - 17*y/9
9*x+17*y = -3
Looking for similar summands in the left part:
9*x + 17*y = -3
Move the summands with the other variables
from left part to right part, we given:
$$9 x = - 17 y - 3$$
Divide both parts of the equation by 9
x = -3 - 17*y / (9)
We get the answer: x = -1/3 - 17*y/9
