The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$3 x = 15 - 2 x$$
Move the summands with the unknown x
from the right part to the left part:
$$5 x = 15$$
Divide both parts of the equation by 5
We get the answer: x = 3
3*x+2 = 17-2*x
Move free summands (without x)
from left part to right part, we given:
$$3 x = 15 - 2 x$$
Move the summands with the unknown x
from the right part to the left part:
$$5 x = 15$$
Divide both parts of the equation by 5
x = 15 / (5)
We get the answer: x = 3
