The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move the summands with the unknown x
from the right part to the left part:
$$17 x = -2$$
Divide both parts of the equation by 17
We get the answer: x = -2/17
(|3|)*x*(|-5|) = -2*x-2
Expand brackets in the left part
3x-5 = -2*x-2
Move the summands with the unknown x
from the right part to the left part:
$$17 x = -2$$
Divide both parts of the equation by 17
x = -2 / (17)
We get the answer: x = -2/17
