The solution
Detail solution
Given the linear equation:
Looking for similar summands in the right part:
Move free summands (without x)
from left part to right part, we given:
$$5 x = 7 x - 14$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-2\right) x = -14$$
Divide both parts of the equation by -2
We get the answer: x = 7
14+5*x = 4*x+3*x
Looking for similar summands in the right part:
14 + 5*x = 7*x
Move free summands (without x)
from left part to right part, we given:
$$5 x = 7 x - 14$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-2\right) x = -14$$
Divide both parts of the equation by -2
x = -14 / (-2)
We get the answer: x = 7
