The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 7 x = 3 x + 40$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-10\right) x = 40$$
Divide both parts of the equation by -10
We get the answer: x = -4
-7*x-40 = 3*x
Move free summands (without x)
from left part to right part, we given:
$$- 7 x = 3 x + 40$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-10\right) x = 40$$
Divide both parts of the equation by -10
x = 40 / (-10)
We get the answer: x = -4
