WebSolve the inequality for a a + b > c We subtract b from both sides: a + b − b > c − b a > c − b If we multiply or divide by a negative number than we must reverse the order of the inequality If c is positive (and not zero) and a < b, then ac < bc and a/c < b/c If c is negative (and not zero) and a < b, then ac > bc and a/c > b/c Video lesson WebNov 16, 2024 · Sure enough, when multiplying by a positive number the direction of the inequality remains the same, however when multiplying by a negative number the direction of the inequality does change. Okay, let’s solve some inequalities. We will start off with inequalities that only have a single inequality in them.
WebOct 6, 2024 · In general, given any algebraic expression X and any positive number p: If X ≤ p then − p ≤ X ≤ p. This theorem holds true for strict inequalities as well. In other words, we can convert any absolute value inequality involving " less than " into a compound inequality which can be solved as usual.
