The solution
Detail solution
Given the linear equation:
Move free summands (without y)
from left part to right part, we given:
$$- 3 y = 7$$
Divide both parts of the equation by -3
We get the answer: y = -7/3
2*1-3*y = 9
Move free summands (without y)
from left part to right part, we given:
$$- 3 y = 7$$
Divide both parts of the equation by -3
y = 7 / (-3)
We get the answer: y = -7/3
