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:
$$0 = \frac{288 x}{17} - 4$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-288\right) x}{17} = -4$$
Divide both parts of the equation by -288/17
We get the answer: x = 17/72
2 = 17*x-1/17*x-2
Looking for similar summands in the right part:
2 = -2 + 288*x/17
Move free summands (without x)
from left part to right part, we given:
$$0 = \frac{288 x}{17} - 4$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-288\right) x}{17} = -4$$
Divide both parts of the equation by -288/17
x = -4 / (-288/17)
We get the answer: x = 17/72
