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:
$$4 x = 24$$
Divide both parts of the equation by 4
We get the answer: x = 6
15-4*(7-x) = 11
Expand brackets in the left part
15-4*7+4*x = 11
Looking for similar summands in the left part:
-13 + 4*x = 11
Move free summands (without x)
from left part to right part, we given:
$$4 x = 24$$
Divide both parts of the equation by 4
x = 24 / (4)
We get the answer: x = 6
