The solution
Detail solution
Given the equation:
Expand expressions:
Reducing, you get:
Move free summands (without x)
from left part to right part, we given:
Move the summands with the other variables
from left part to right part, we given:
Divide both parts of the equation by (-7*x + x*y)/x
We get the answer: x = 4
(x-4)*(y-7) = 0
Expand expressions:
28 - 7*x - 4*y + x*y = 0
Reducing, you get:
28 - 7*x - 4*y + x*y = 0
Move free summands (without x)
from left part to right part, we given:
Move the summands with the other variables
from left part to right part, we given:
Divide both parts of the equation by (-7*x + x*y)/x
x = -28 + 4*y / ((-7*x + x*y)/x)
We get the answer: x = 4
