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:
$$- 6 x = 9 - 4 x$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-2\right) x = 9$$
Divide both parts of the equation by -2
We get the answer: x = -9/2
2-3*(2*x+2) = 5-4*x
Expand brackets in the left part
2-3*2*x-3*2 = 5-4*x
Looking for similar summands in the left part:
-4 - 6*x = 5-4*x
Move free summands (without x)
from left part to right part, we given:
$$- 6 x = 9 - 4 x$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-2\right) x = 9$$
Divide both parts of the equation by -2
x = 9 / (-2)
We get the answer: x = -9/2
