The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$7 x = x + 54$$
Move the summands with the unknown x
from the right part to the left part:
$$6 x = 54$$
Divide both parts of the equation by 6
We get the answer: x = 9
7*x-30 = 24+x
Move free summands (without x)
from left part to right part, we given:
$$7 x = x + 54$$
Move the summands with the unknown x
from the right part to the left part:
$$6 x = 54$$
Divide both parts of the equation by 6
x = 54 / (6)
We get the answer: x = 9
