The solution
Detail solution
Given the linear equation:
Expand brackets in the right part
Looking for similar summands in the right part:
Move free summands (without x)
from left part to right part, we given:
$$5 x = 8 x + 15$$
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
5*x+8 = 9+(8*x+14)
Expand brackets in the right part
5*x+8 = 9+8*x+14
Looking for similar summands in the right part:
8 + 5*x = 23 + 8*x
Move free summands (without x)
from left part to right part, we given:
$$5 x = 8 x + 15$$
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
