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:
$$16 x = 1$$
Divide both parts of the equation by 16
We get the answer: x = 1/16
(7*x+1)+(9*x+3) = 5
Expand brackets in the left part
7*x+1+9*x+3 = 5
Looking for similar summands in the left part:
4 + 16*x = 5
Move free summands (without x)
from left part to right part, we given:
$$16 x = 1$$
Divide both parts of the equation by 16
x = 1 / (16)
We get the answer: x = 1/16
