The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$7 x = 27 - 2 x$$
Move the summands with the unknown x
from the right part to the left part:
$$9 x = 27$$
Divide both parts of the equation by 9
We get the answer: x = 3
7*x+3 = 30-2*x
Move free summands (without x)
from left part to right part, we given:
$$7 x = 27 - 2 x$$
Move the summands with the unknown x
from the right part to the left part:
$$9 x = 27$$
Divide both parts of the equation by 9
x = 27 / (9)
We get the answer: x = 3
