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:
$$5 y = 4$$
Divide both parts of the equation by 5
We get the answer: y = 4/5
14+2*y+3*y = 18
Looking for similar summands in the left part:
14 + 5*y = 18
Move free summands (without y)
from left part to right part, we given:
$$5 y = 4$$
Divide both parts of the equation by 5
y = 4 / (5)
We get the answer: y = 4/5
