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:
$$6 y = 9 - 3 y$$
Move the summands with the unknown y
from the right part to the left part:
$$9 y = 9$$
Divide both parts of the equation by 9
We get the answer: y = 1
6*(y+2) = 21-3*y
Expand brackets in the left part
6*y+6*2 = 21-3*y
Move free summands (without y)
from left part to right part, we given:
$$6 y = 9 - 3 y$$
Move the summands with the unknown y
from the right part to the left part:
$$9 y = 9$$
Divide both parts of the equation by 9
y = 9 / (9)
We get the answer: y = 1
