The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move the summands with the other variables
from left part to right part, we given:
$$- 7 x = 2 y + 16$$
Divide both parts of the equation by -7
We get the answer: x = -16/7 - 2*y/7
-7*x-2*y = 16
Looking for similar summands in the left part:
-7*x - 2*y = 16
Move the summands with the other variables
from left part to right part, we given:
$$- 7 x = 2 y + 16$$
Divide both parts of the equation by -7
x = 16 + 2*y / (-7)
We get the answer: x = -16/7 - 2*y/7
