The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$4 x = 9 x - 60$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-5\right) x = -60$$
Divide both parts of the equation by -5
We get the answer: x = 12
4*x+60 = 9*x
Move free summands (without x)
from left part to right part, we given:
$$4 x = 9 x - 60$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-5\right) x = -60$$
Divide both parts of the equation by -5
x = -60 / (-5)
We get the answer: x = 12
