The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without y)
from left part to right part, we given:
$$- 4 y = 12$$
Divide both parts of the equation by -4
We get the answer: y = -3
11*y-(15*y+8) = 4
Expand brackets in the left part
11*y-15*y-8 = 4
Looking for similar summands in the left part:
-8 - 4*y = 4
Move free summands (without y)
from left part to right part, we given:
$$- 4 y = 12$$
Divide both parts of the equation by -4
y = 12 / (-4)
We get the answer: y = -3
