The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$36 x = 48 x + 42$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-12\right) x = 42$$
Divide both parts of the equation by -12
We get the answer: x = -7/2
36*x-42 = 48*x
Move free summands (without x)
from left part to right part, we given:
$$36 x = 48 x + 42$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-12\right) x = 42$$
Divide both parts of the equation by -12
x = 42 / (-12)
We get the answer: x = -7/2
