Solving Inequalities with Negative Coefficients

Why is it often easier to work with positive coefficients in inequalities?

• Negative coefficients are not allowed in inequalities.

• Positive coefficients simplify the arithmetic.

• Positive coefficients make the inequality true.

• Positive coefficients are always larger.
