The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Move free summands (without x)
from left part to right part, we given:
$$11 x = 7 x + \frac{16}{5}$$
Move the summands with the unknown x
from the right part to the left part:
$$4 x = \frac{16}{5}$$
Divide both parts of the equation by 4
We get the answer: x = 4/5
11*x-(9/5) = 7*x+(7/5)
Expand brackets in the left part
11*x-9/5 = 7*x+(7/5)
Expand brackets in the right part
11*x-9/5 = 7*x+7/5
Move free summands (without x)
from left part to right part, we given:
$$11 x = 7 x + \frac{16}{5}$$
Move the summands with the unknown x
from the right part to the left part:
$$4 x = \frac{16}{5}$$
Divide both parts of the equation by 4
x = 16/5 / (4)
We get the answer: x = 4/5
