The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$3 x = 10 x - 14$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-7\right) x = -14$$
Divide both parts of the equation by -7
We get the answer: x = 2
3*x-1 = 10*x-15
Move free summands (without x)
from left part to right part, we given:
$$3 x = 10 x - 14$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-7\right) x = -14$$
Divide both parts of the equation by -7
x = -14 / (-7)
We get the answer: x = 2
