The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 4 x = 3 x - 49$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-7\right) x = -49$$
Divide both parts of the equation by -7
We get the answer: x = 7
9-4*x = 3*x-40
Move free summands (without x)
from left part to right part, we given:
$$- 4 x = 3 x - 49$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-7\right) x = -49$$
Divide both parts of the equation by -7
x = -49 / (-7)
We get the answer: x = 7
