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:
$$- 3 x = 26 - 5 x$$
Move the summands with the unknown x
from the right part to the left part:
$$2 x = 26$$
Divide both parts of the equation by 2
We get the answer: x = 13
10-3*(x+4) = 24-5*x
Expand brackets in the left part
10-3*x-3*4 = 24-5*x
Looking for similar summands in the left part:
-2 - 3*x = 24-5*x
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = 26 - 5 x$$
Move the summands with the unknown x
from the right part to the left part:
$$2 x = 26$$
Divide both parts of the equation by 2
x = 26 / (2)
We get the answer: x = 13
