Command

Solve

Inequality
2*x+4*y < 8

  1. an inequality in which left side of inequality smaller than right side of inequality; the left side of the inequality is a sum that consists of 2 terms; the 1st term of the sum is equal to a product containing 2 factors; the 1st factor of the product is equal to two; the 2nd factor of the product is equal to x; the 2nd term of the sum is equal to a product that comprises 2 factors; the 1st factor of the product is equal to four; the 2nd factor of the product is equal to y; the right side of the inequality is equal to eight;
  2. two multiplied by x plus four times y smaller than eight;
Variable
Result
A nonpolynomial inequality has been used, so the solution set may be incorrect.

Exact

<<y < 2-x/2>>

  1. an inequality in which left side of inequality smaller than right side of inequality; the left side of the inequality is equal to y; the right side of the inequality is a sum that contains 2 terms; the 1st term of the sum is two; the 2nd term of the sum is a negative quotient: dividend of the quotient is x; divisor of the quotient is two;
  2. open bracket y smaller than two plus negative x over two close bracket;


Approximate

<<y < 2.0-0.5*x>>

  1. an inequality in which left side of inequality smaller than right side of inequality. The left side of the inequality is equal to y. The right side of the inequality is equal to a sum that contains 2 terms. The 1st term of the sum is equal to two. The 2nd term of the sum is a negative product that consists of 2 factors. The 1st factor of the product is zero point five. The 2nd factor of the product is equal to x.
  2. open parenthesis y smaller than two plus negative zero point five multiplied by x close parenthesis;
