The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = 4 x + 28$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-7\right) x = 28$$
Divide both parts of the equation by -7
We get the answer: x = -4
-3*x-17 = 4*x+11
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = 4 x + 28$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-7\right) x = 28$$
Divide both parts of the equation by -7
x = 28 / (-7)
We get the answer: x = -4
