[src]
8 - 5*x = 2*(x + 2) + (4*x + 2)*2
$$8 - 5 x = 2 \left(x + 2\right) + 2 \left(4 x + 2\right)$$
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:
$$- 5 x = 10 x$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-15\right) x = 0$$
Divide both parts of the equation by -15
We get the answer: x = 0
8-5*x = 2*(x+2)+(4*x+2)*2
Expand brackets in the right part
8-5*x = 2*x+2*2+4*x*2+2*2
Looking for similar summands in the right part:
8 - 5*x = 8 + 10*x
Move free summands (without x)
from left part to right part, we given:
$$- 5 x = 10 x$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-15\right) x = 0$$
Divide both parts of the equation by -15
x = 0 / (-15)
We get the answer: x = 0
