[src]
5*x + 8 + -8*x - 14 = 9
$$\left(- 8 x - 14\right) + \left(5 x + 8\right) = 9$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = 15$$
Divide both parts of the equation by -3
We get the answer: x = -5
(5*x+8)-(8*x+14) = 9
Expand brackets in the left part
5*x+8-8*x-14 = 9
Looking for similar summands in the left part:
-6 - 3*x = 9
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = 15$$
Divide both parts of the equation by -3
x = 15 / (-3)
We get the answer: x = -5
