Inequality
abs(2*x-10) < 5

  1. an inequality in which left side of inequality smaller than right side of inequality. The left side of the inequality is absolute value of a sum containing 2 terms. The 1st term of the sum is a product that consists of 2 factors. The 1st factor of the product is equal to two. The 2nd factor of the product is x. The 2nd term of the sum is negative ten. The right side of the inequality is equal to five.
  2. absolute value of two times x plus negative ten less than five.
Variable
Result
A nonpolynomial inequality has been used, so the solution set may be incorrect.

Exact

<<5/2 < x,x < 15/2>>

  1. an inequality in which left side of inequality less than right side of inequality. The left side of the inequality is equal to a fraction: the numerator of the fraction is five. The denominator of the fraction is two. The right side of the inequality is x new line an inequality in which left side of inequality smaller than right side of inequality. The left side of the inequality is equal to x. The right side of the inequality is equal to a rational expression: the numerator of the rational expression is fifteen. The denominator of the rational expression is two.
  2. left parenthesis five divided by two less than x new line x less than fifteen over two right parenthesis.


Approximate

<<2.5 < x,x < 7.5>>

  1. an inequality in which left side of inequality smaller than right side of inequality; the left side of the inequality is two point and five tenth; the right side of the inequality is equal to x new line an inequality in which left side of inequality smaller than right side of inequality; the left side of the inequality is x; the right side of the inequality is equal to seven point and five tenth;
  2. open parenthesis two point five less than x new line x less than seven point and five tenth close parenthesis.
