The solution
You have entered
[src]
-x - 4 + 5*(x + 3) = -1 - x - 2
$$\left(- x - 4\right) + 5 \left(x + 3\right) = \left(- x - 1\right) - 2$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Looking for similar summands in the left part:
Looking for similar summands in the right part:
Move free summands (without x)
from left part to right part, we given:
$$4 x = - x - 14$$
Move the summands with the unknown x
from the right part to the left part:
$$5 x = -14$$
Divide both parts of the equation by 5
We get the answer: x = -14/5
-x-4+5*(x+3) = (-1-x)-2
Expand brackets in the left part
-x-4+5*x+5*3 = (-1-x)-2
Expand brackets in the right part
-x-4+5*x+5*3 = -1-x-2
Looking for similar summands in the left part:
11 + 4*x = -1-x-2
Looking for similar summands in the right part:
11 + 4*x = -3 - x
Move free summands (without x)
from left part to right part, we given:
$$4 x = - x - 14$$
Move the summands with the unknown x
from the right part to the left part:
$$5 x = -14$$
Divide both parts of the equation by 5
x = -14 / (5)
We get the answer: x = -14/5
