[src]
8*x + 3 + -10*x - 6 = 9
$$\left(- 10 x - 6\right) + \left(8 x + 3\right) = 9$$
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:
$$- 2 x = 12$$
Divide both parts of the equation by -2
We get the answer: x = -6
(8*x+3)-(10*x+6) = 9
Expand brackets in the left part
8*x+3-10*x-6 = 9
Looking for similar summands in the left part:
-3 - 2*x = 9
Move free summands (without x)
from left part to right part, we given:
$$- 2 x = 12$$
Divide both parts of the equation by -2
x = 12 / (-2)
We get the answer: x = -6
