The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without y)
from left part to right part, we given:
$$- y = \frac{26}{5}$$
Divide both parts of the equation by -1
We get the answer: y = -26/5
-y-(6/5) = 4
Expand brackets in the left part
-y-6/5 = 4
Move free summands (without y)
from left part to right part, we given:
$$- y = \frac{26}{5}$$
Divide both parts of the equation by -1
y = 26/5 / (-1)
We get the answer: y = -26/5
