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:
$$- 5 y = - 22 x - 46$$
Divide both parts of the equation by -5
We get the answer: y = 46/5 + 22*x/5
22*x-5*y = -46
Looking for similar summands in the left part:
-5*y + 22*x = -46
Move the summands with the other variables
from left part to right part, we given:
$$- 5 y = - 22 x - 46$$
Divide both parts of the equation by -5
y = -46 - 22*x / (-5)
We get the answer: y = 46/5 + 22*x/5
