[src]
x + 74*x + 2 = x + 72*x - 4
$$\left(x + 74 x\right) + 2 = \left(x + 72 x\right) - 4$$
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Looking for similar summands in the right part:
Move free summands (without x)
from left part to right part, we given:
$$75 x = 73 x - 6$$
Move the summands with the unknown x
from the right part to the left part:
$$2 x = -6$$
Divide both parts of the equation by 2
We get the answer: x = -3
x+74*x+2 = x+72*x-4
Looking for similar summands in the left part:
2 + 75*x = x+72*x-4
Looking for similar summands in the right part:
2 + 75*x = -4 + 73*x
Move free summands (without x)
from left part to right part, we given:
$$75 x = 73 x - 6$$
Move the summands with the unknown x
from the right part to the left part:
$$2 x = -6$$
Divide both parts of the equation by 2
x = -6 / (2)
We get the answer: x = -3
