An inequality requires an inequality sign, usually "less than", "less-than-or-equal", "greater than", or "greater than or equal".

Assuming one of these inequality signs is between the "4x" and the "12", for example:

4x < 12,

just divide both sides by 4. Just as when you solve equations, the idea is to isolate the variable on one side.

Q: What operation gives the solution to the inequality 4x 12?

Division by 4: 4x â‰¤ 12 divide both sides by 4: x â‰¤ 3

-6+m>12 +6 +6 m>18 20>18 Substitute 20 in for m, and that makes the inequality correct.

To solve the inequality 3x ≥ 12, you need to isolate x. First, divide both sides by 3 to get x ≥ 4. This means that any value of x that is greater than or equal to 4 satisfies the inequality. In interval notation, the solution is [4, ∞).

4g < 7g+12 Subtract 7g from both sides: 4g-7g < 12 -3g < 12 Divide both sides by -3 and reverse the inequality sign: g > -4 on the number line

'r' is equal to, or anywhere between, -13 and 38 .

There is no solution to: 4(2x + 2) + 12 > 1004(2x + 2) + 12 > 100 For 4(2x + 2) + 12 > 1004(2x + 2) + 12 to have a solution x < -1 which makes 1004(2x + 2) + 12 < 12, BUT 1004(2x + 2) + 12 is supposed to be greater than 100. Perhaps there is a missing operator in the digits of 1004?

-30

The inequality that fits this condition is that x is greater than or equal to -12.

Without an equality sign the given expression is not an equation and so therefore a solution is not possible.
