The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$- 7 x = 17 - 6 x$$
Move the summands with the unknown x
from the right part to the left part:
$$- x = 17$$
Divide both parts of the equation by -1
We get the answer: x = -17
9-7*(x+3) = 5-6*x
Expand brackets in the left part
9-7*x-7*3 = 5-6*x
Looking for similar summands in the left part:
-12 - 7*x = 5-6*x
Move free summands (without x)
from left part to right part, we given:
$$- 7 x = 17 - 6 x$$
Move the summands with the unknown x
from the right part to the left part:
$$- x = 17$$
Divide both parts of the equation by -1
x = 17 / (-1)
We get the answer: x = -17
