The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move free summands (without t)
from left part to right part, we given:
$$- 3 t = 4$$
Divide both parts of the equation by -3
We get the answer: t = -4/3
2*t-15/3*t-4 = 0
Looking for similar summands in the left part:
-4 - 3*t = 0
Move free summands (without t)
from left part to right part, we given:
$$- 3 t = 4$$
Divide both parts of the equation by -3
t = 4 / (-3)
We get the answer: t = -4/3
