How do you solve 4 is greater than or equal to 5 y over -2 keeping in mind that only the y is over the negative?
To solve 4 ≥ 5y/-2 assuming normal algebraic rules regarding numbers and letters that are next to each other meaning multiply (and not as in a mixed number fraction):
4 ≥ 5y/-2 → 4 ≥ 5y/-2 (multiplying a fraction by a whole number → multiply numerator by the number)
→ 4 ≥ -5y/2 (make the denominator positive, so negate the numerator)
→ 8 ≥ -5y (multiply both sides by 2)*
→ 5y ≥ -8 (take the -5y and the 8 to the opposite sides, changing their signs)
→ y ≥ -8/5 (divide both sides by 5)
Thus any value of y greater than or equal to -8/5 = -13/5 is a solution.
* Multiplying (or dividing) both sides of an inequality by a negative number changes the direction of the inequality: greater than becomes less than and vice verse. By ensuring that the top of the negative "fraction" is the negative number and the bottom is positive, this change of inequality does not need to be remembered as a negative number is not used to multiply both sides.

How do you solve the inequality2x -10 6?
This isn't an inequality, since there is no less-than, greater-than, less-than-or-equal, or greater-than-or-equal sign. However, solving inequalities is similar to solving equations; however, when you multiply by a negative number, you must change the direction of the inequality sign.
How do you solve 10 greater than or equal to negative x?
10 ≥ -xUsing the rule that if a ≥ b, then -1*a ≤ -1*b-1*10 ≤ -1*xTherefore -10 ≤ x or x ≥ -10
What is the difference between inpuality and equation?
I assume you mean "inequality". An equation has an equal sign; an inequality has one of the inequality signs instead of an equal sign. These signs are: * Greater than * Greater than or equal * Less than * Less than or equal To solve an inequality, the main point to consider is that if you multiply or divide both sides by a negative number, you must invert the inequality sign. For example, if you multiply both sides by (-2), a greater-than sign would need to be changed to a less-than sign.

How do you solve 5 minus negative 6?
To solve the problem 5 - -6, think of it as 5 + 6. You can do this because two negative numbers equal as positive number, and similarly two negative signs equal a positive. Therefore 5 --6 is 11.

How do you solve an inequality with fractions and variables on both sides?
You solve an inequality the same way you solve an equality. You add and subtract, multiply and divide, both sides by the same value in order to isolate one of the variables. The only extra thing you need to remember is that if you multiply or divide by a negative number, you must reverse the order of the inequality, i.e. less than or equal becomes greater than or equal.
