The solution
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:
$$- 4 x = -40$$
Divide both parts of the equation by -4
We get the answer: x = 10
12*x-16*(x-3) = 8
Expand brackets in the left part
12*x-16*x+16*3 = 8
Looking for similar summands in the left part:
48 - 4*x = 8
Move free summands (without x)
from left part to right part, we given:
$$- 4 x = -40$$
Divide both parts of the equation by -4
x = -40 / (-4)
We get the answer: x = 10
