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:
$$7 x = 28$$
Divide both parts of the equation by 7
We get the answer: x = 4
16-7*(5-x) = 9
Expand brackets in the left part
16-7*5+7*x = 9
Looking for similar summands in the left part:
-19 + 7*x = 9
Move free summands (without x)
from left part to right part, we given:
$$7 x = 28$$
Divide both parts of the equation by 7
x = 28 / (7)
We get the answer: x = 4
