The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without x)
from left part to right part, we given:
$$30 x = 9 x + 63$$
Move the summands with the unknown x
from the right part to the left part:
$$21 x = 63$$
Divide both parts of the equation by 21
We get the answer: x = 3
-6*(9-5*x) = 9*x+9
Expand brackets in the left part
-6*9+6*5*x = 9*x+9
Move free summands (without x)
from left part to right part, we given:
$$30 x = 9 x + 63$$
Move the summands with the unknown x
from the right part to the left part:
$$21 x = 63$$
Divide both parts of the equation by 21
x = 63 / (21)
We get the answer: x = 3
