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:
$$3 y = -7$$
Divide both parts of the equation by 3
We get the answer: y = -7/3
7+(3*y-8) = -8
Expand brackets in the left part
7+3*y-8 = -8
Looking for similar summands in the left part:
-1 + 3*y = -8
Move free summands (without y)
from left part to right part, we given:
$$3 y = -7$$
Divide both parts of the equation by 3
y = -7 / (3)
We get the answer: y = -7/3
