The solution
Detail solution
Given the linear equation:
Expand brackets in the right part
Looking for similar summands in the right part:
Move free summands (without x)
from left part to right part, we given:
$$0 = - 5 x - 57$$
Move the summands with the unknown x
from the right part to the left part:
$$5 x = -57$$
Divide both parts of the equation by 5
We get the answer: x = -57/5
-6 = -9*(7+x)+4*x
Expand brackets in the right part
-6 = -9*7-9*x+4*x
Looking for similar summands in the right part:
-6 = -63 - 5*x
Move free summands (without x)
from left part to right part, we given:
$$0 = - 5 x - 57$$
Move the summands with the unknown x
from the right part to the left part:
$$5 x = -57$$
Divide both parts of the equation by 5
x = -57 / (5)
We get the answer: x = -57/5
