The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move free summands (without y)
from left part to right part, we given:
$$- y = \frac{1}{5}$$
Divide both parts of the equation by -1
We get the answer: y = -1/5
2*y+9/5-3*y = 2
Looking for similar summands in the left part:
9/5 - y = 2
Move free summands (without y)
from left part to right part, we given:
$$- y = \frac{1}{5}$$
Divide both parts of the equation by -1
y = 1/5 / (-1)
We get the answer: y = -1/5
