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:
$$- 3 x = 16 - 5 x$$
Move the summands with the unknown x
from the right part to the left part:
$$2 x = 16$$
Divide both parts of the equation by 2
We get the answer: x = 8
10-3*(x+4) = 14-5*x
Expand brackets in the left part
10-3*x-3*4 = 14-5*x
Looking for similar summands in the left part:
-2 - 3*x = 14-5*x
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = 16 - 5 x$$
Move the summands with the unknown x
from the right part to the left part:
$$2 x = 16$$
Divide both parts of the equation by 2
x = 16 / (2)
We get the answer: x = 8
