WebIf you're dealing with an inequality and you multiply or divide both sides of an equation by a negative number, you have to swap the inequality. So in this case, the less than becomes …
WebThe final answer is just \left ( { - 1,4} \right) (−1,4). Example 4: Solve the rational inequality below. This rational inequality is not in general form. The right-hand side must be zero. The first step is to get rid of the constant on that side by subtracting both sides by 1 1. WebTake the solution (s) and put them in the original equation to see if they really work. Example: solve for x: 2x x − 3 + 3 = 6 x − 3 (x≠3) We have said x≠3 to avoid a division by zero. Let's multiply through by (x − 3): 2x + 3 (x−3) = 6 Bring the 6 to the left: 2x + 3 (x−3) − 6 = 0 Expand and solve: 2x + 3x − 9 − 6 = 0 5x − 15 = 0 5 (x − 3) = 0
WebAs we just saw, putting minuses in front of a and b changes the direction of the inequality. This is called the "Additive Inverse": If a < b then −a > −b. If a > b then −a < −b. This is really the same as multiplying by (-1), and that is why it changes direction. Example: Alex has more money than Billy, and so Alex is ahead.

This means they are NOT inequalities. 3+5 = 8. x + 2 = 10. x + y = 9. So... let's think about what the prefix in means in in equality. The prefix in means "not". So, an inequality means "not equal". tebessa fm
