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:
$$8 x = 64$$
Divide both parts of the equation by 8
We get the answer: x = 8
3*x-5*(2-x) = 54
Expand brackets in the left part
3*x-5*2+5*x = 54
Looking for similar summands in the left part:
-10 + 8*x = 54
Move free summands (without x)
from left part to right part, we given:
$$8 x = 64$$
Divide both parts of the equation by 8
x = 64 / (8)
We get the answer: x = 8
