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:
$$6 y = 30$$
Divide both parts of the equation by 6
We get the answer: y = 5
3*(2*y-7) = 9
Expand brackets in the left part
3*2*y-3*7 = 9
Move free summands (without y)
from left part to right part, we given:
$$6 y = 30$$
Divide both parts of the equation by 6
y = 30 / (6)
We get the answer: y = 5
