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:
$$4 y = 16$$
Divide both parts of the equation by 4
We get the answer: y = 4
3*y-(5-y) = 11
Expand brackets in the left part
3*y-5+y = 11
Looking for similar summands in the left part:
-5 + 4*y = 11
Move free summands (without y)
from left part to right part, we given:
$$4 y = 16$$
Divide both parts of the equation by 4
y = 16 / (4)
We get the answer: y = 4
