The solution
Detail solution
Given the linear equation:
Move the summands with the unknown x
from the right part to the left part:
$$6 x = -9$$
Divide both parts of the equation by 6
We get the answer: x = -3/2
-4*x = -10*x-9
Move the summands with the unknown x
from the right part to the left part:
$$6 x = -9$$
Divide both parts of the equation by 6
x = -9 / (6)
We get the answer: x = -3/2
