WebStep by step guide to solve one-step inequalities. Similar to equations, first isolate the variable by using the inverse operation. For dividing or multiplying both sides by negative numbers, flip the direction of the inequality sign. One–Step Inequalities. 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

WebYou can put the values of x into the inequality as a solution and work it out. If the remaining (or simplified) part of the equation is correct, then that solution out of the number of solutions you got for x in the inequality is correct. 1 comment ( 4 votes) Ian Fischer 5 years ago What is the answer?

When we add or subtract the same number on both sides of the truth of the inequality doesn't change. This holds true for all numbers: x > y → x < y →. x + z > y + z → x + z < y + z →. shanghai labor arbitration

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. Example 2.6.7: 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.
