A inequation with variable

The solution

You have entered [src]
5 - 11*x <= 2
511x25 - 11 x \leq 2
5 - 11*x <= 2
Detail solution
Given the inequality:
511x25 - 11 x \leq 2
To solve this inequality, we must first solve the corresponding equation:
511x=25 - 11 x = 2
Solve:
Given the linear equation:
5-11*x = 2

Move free summands (without x)
from left part to right part, we given:
11x=3- 11 x = -3
Divide both parts of the equation by -11
x = -3 / (-11)

x1=311x_{1} = \frac{3}{11}
x1=311x_{1} = \frac{3}{11}
This roots
x1=311x_{1} = \frac{3}{11}
is the points with change the sign of the inequality expression.
First define with the sign to the leftmost point:
x0x1x_{0} \leq x_{1}
For example, let's take the point
x0=x1110x_{0} = x_{1} - \frac{1}{10}
=
110+311- \frac{1}{10} + \frac{3}{11}
=
19110\frac{19}{110}
substitute to the expression
511x25 - 11 x \leq 2
5111911025 - \frac{11 \cdot 19}{110} \leq 2

Then

no execute
the solution of our inequality is:
