The solution
Detail solution
Given the linear equation:
Expand brackets in the right part
Looking for similar summands in the right part:
Move free summands (without x)
from left part to right part, we given:
$$10 x = 37 x + 27$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-27\right) x = 27$$
Divide both parts of the equation by -27
We get the answer: x = -1
10*x-9 = 6*(7*x+3)-5*x
Expand brackets in the right part
10*x-9 = 6*7*x+6*3-5*x
Looking for similar summands in the right part:
-9 + 10*x = 18 + 37*x
Move free summands (without x)
from left part to right part, we given:
$$10 x = 37 x + 27$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-27\right) x = 27$$
Divide both parts of the equation by -27
x = 27 / (-27)
We get the answer: x = -1
