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:
$$9 y = \frac{12}{5}$$
Divide both parts of the equation by 9
We get the answer: y = 4/15
9*y-(12/5) = 0
Expand brackets in the left part
9*y-12/5 = 0
Move free summands (without y)
from left part to right part, we given:
$$9 y = \frac{12}{5}$$
Divide both parts of the equation by 9
y = 12/5 / (9)
We get the answer: y = 4/15
