The solution
You have entered
[src]
5*x + 12 - 10*x + 12 = 48
$$\left(- 10 x + \left(5 x + 12\right)\right) + 12 = 48$$
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$- 5 x = 24$$
Divide both parts of the equation by -5
We get the answer: x = -24/5
5*x+12-10*x+12 = 48
Looking for similar summands in the left part:
24 - 5*x = 48
Move free summands (without x)
from left part to right part, we given:
$$- 5 x = 24$$
Divide both parts of the equation by -5
x = 24 / (-5)
We get the answer: x = -24/5
