The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$17 x = 20 x + 15$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-3\right) x = 15$$
Divide both parts of the equation by -3
We get the answer: x = -5
17*x-8 = 20*x+7
Move free summands (without x)
from left part to right part, we given:
$$17 x = 20 x + 15$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-3\right) x = 15$$
Divide both parts of the equation by -3
x = 15 / (-3)
We get the answer: x = -5
