2*(8 - x) + 8 = 4*(3*x - 1)
$$2 \left(8 - x\right) + 8 = 4 \left(3 x - 1\right)$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$- 2 x = 12 x - 28$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-14\right) x = -28$$
Divide both parts of the equation by -14
We get the answer: x = 2
2*(8-x)+8 = 4*(3*x-1)
Expand brackets in the left part
2*8-2*x+8 = 4*(3*x-1)
Expand brackets in the right part
2*8-2*x+8 = 4*3*x-4*1
Looking for similar summands in the left part:
24 - 2*x = 4*3*x-4*1
Move free summands (without x)
from left part to right part, we given:
$$- 2 x = 12 x - 28$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-14\right) x = -28$$
Divide both parts of the equation by -14
x = -28 / (-14)
We get the answer: x = 2
