4*(5 - n) - 3*(2*n + 7) = 0
$$4 \left(5 - n\right) - 3 \left(2 n + 7\right) = 0$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without n)
from left part to right part, we given:
$$- 10 n = 1$$
Divide both parts of the equation by -10
We get the answer: n = -1/10
4*(5-n)-3*(2*n+7) = 0
Expand brackets in the left part
4*5-4*n-3*2*n-3*7 = 0
Looking for similar summands in the left part:
-1 - 10*n = 0
Move free summands (without n)
from left part to right part, we given:
$$- 10 n = 1$$
Divide both parts of the equation by -10
n = 1 / (-10)
We get the answer: n = -1/10
