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:
$$15 x = 30$$
Divide both parts of the equation by 15
We get the answer: x = 2
8-5*(4-3*x) = 18
Expand brackets in the left part
8-5*4+5*3*x = 18
Looking for similar summands in the left part:
-12 + 15*x = 18
Move free summands (without x)
from left part to right part, we given:
$$15 x = 30$$
Divide both parts of the equation by 15
x = 30 / (15)
We get the answer: x = 2
