The solution
Detail solution
Given the linear equation:
Expand brackets in the right part
Looking for similar summands in the right part:
Move free summands (without x)
from left part to right part, we given:
$$3 x = x + 18$$
Move the summands with the unknown x
from the right part to the left part:
$$2 x = 18$$
Divide both parts of the equation by 2
We get the answer: x = 9
3*x-3 = 7*x-3*(2*x-5)
Expand brackets in the right part
3*x-3 = 7*x-3*2*x+3*5
Looking for similar summands in the right part:
-3 + 3*x = 15 + x
Move free summands (without x)
from left part to right part, we given:
$$3 x = x + 18$$
Move the summands with the unknown x
from the right part to the left part:
$$2 x = 18$$
Divide both parts of the equation by 2
x = 18 / (2)
We get the answer: x = 9
