The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without x)
from left part to right part, we given:
$$81 x = 4 x + 77$$
Move the summands with the unknown x
from the right part to the left part:
$$77 x = 77$$
Divide both parts of the equation by 77
We get the answer: x = 1
-9*(8-9*x) = 4*x+5
Expand brackets in the left part
-9*8+9*9*x = 4*x+5
Move free summands (without x)
from left part to right part, we given:
$$81 x = 4 x + 77$$
Move the summands with the unknown x
from the right part to the left part:
$$77 x = 77$$
Divide both parts of the equation by 77
x = 77 / (77)
We get the answer: x = 1
