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:
$$5 x = 37 x + 16$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-32\right) x = 16$$
Divide both parts of the equation by -32
We get the answer: x = -1/2
5*(x-(16/5)) = 37*x
Expand brackets in the left part
5*x+5*16/5) = 37*x
Move free summands (without x)
from left part to right part, we given:
$$5 x = 37 x + 16$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-32\right) x = 16$$
Divide both parts of the equation by -32
x = 16 / (-32)
We get the answer: x = -1/2
