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:
$$0 = 3 x - 51$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-3\right) x = -51$$
Divide both parts of the equation by -3
We get the answer: x = 17
51 = 4*x-x
Looking for similar summands in the right part:
51 = 3*x
Move free summands (without x)
from left part to right part, we given:
$$0 = 3 x - 51$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-3\right) x = -51$$
Divide both parts of the equation by -3
x = -51 / (-3)
We get the answer: x = 17
