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:
$$15 x = 15$$
Divide both parts of the equation by 15
We get the answer: x = 1
1-5*(2-3*x) = 6
Expand brackets in the left part
1-5*2+5*3*x = 6
Looking for similar summands in the left part:
-9 + 15*x = 6
Move free summands (without x)
from left part to right part, we given:
$$15 x = 15$$
Divide both parts of the equation by 15
x = 15 / (15)
We get the answer: x = 1
