The solution
You have entered
[src]
(2*x - 1)*4 - 8*(2*x - 1)*2 + 16 = 0
$$\left(4 \left(2 x - 1\right) - 2 \cdot 8 \left(2 x - 1\right)\right) + 16 = 0$$
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:
$$- 24 x = -28$$
Divide both parts of the equation by -24
We get the answer: x = 7/6
(2*x-1)*4-8*(2*x-1)*2+16 = 0
Expand brackets in the left part
2*x*4-1*4-8*2*x*2+8*1*2+16 = 0
Looking for similar summands in the left part:
28 - 24*x = 0
Move free summands (without x)
from left part to right part, we given:
$$- 24 x = -28$$
Divide both parts of the equation by -24
x = -28 / (-24)
We get the answer: x = 7/6
