The solution
Detail solution
Given the linear equation:
Move free summands (without y)
from left part to right part, we given:
$$- 8 y = 4 y - 24$$
Move the summands with the unknown y
from the right part to the left part:
$$- 12 y = -24$$
Divide both parts of the equation by -12
We get the answer: y = 2
17-8*y = 4*y-7
Move free summands (without y)
from left part to right part, we given:
$$- 8 y = 4 y - 24$$
Move the summands with the unknown y
from the right part to the left part:
$$- 12 y = -24$$
Divide both parts of the equation by -12
y = -24 / (-12)
We get the answer: y = 2
