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:
$$8 x = 6 x - 24$$
Move the summands with the unknown x
from the right part to the left part:
$$2 x = -24$$
Divide both parts of the equation by 2
We get the answer: x = -12
3*(5*x+8)-7*x = 6*x
Expand brackets in the left part
3*5*x+3*8-7*x = 6*x
Looking for similar summands in the left part:
24 + 8*x = 6*x
Move free summands (without x)
from left part to right part, we given:
$$8 x = 6 x - 24$$
Move the summands with the unknown x
from the right part to the left part:
$$2 x = -24$$
Divide both parts of the equation by 2
x = -24 / (2)
We get the answer: x = -12
