The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$3 x = 7 x + 8$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-4\right) x = 8$$
Divide both parts of the equation by -4
We get the answer: x = -2
3*x-2 = 7*x+6
Move free summands (without x)
from left part to right part, we given:
$$3 x = 7 x + 8$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-4\right) x = 8$$
Divide both parts of the equation by -4
x = 8 / (-4)
We get the answer: x = -2
