7 > 1 this true.
7 - 5 > 1 - 5
2 > - 4 this also is true (remember, numbers grow up from the left to the right in a number line).

What happens if you add or subtract a value to both sides of an inequality?
The direction of the inequality remains unchanged. The direction changes when you divide or multiply both sides by a negative number. It also changes if both sides are raised to a negative exponent.
-5x 4 greater than -2x 31?
-5x + 4 > -2x + 31 add 2x and subtract 4 to both sides; -3x > 27 divide by -3 to both sides and change the symbol of the inequality; x < 9
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.
Simplify the following expression 33z-4-20 z-5?
I am assuming that the original equation is 33z-4-20=z-5. Subtract z from both sides. Add 4 to both sides, as well as add 20 to both sides. Divide both sides by 32.
What it 2t-6 equals 3-t?
2t-6=3-t 3t-6=3 Add t to both sides 3t=9 Add 6 to both sides t=3 Divide both sides by 3
What happens if you add or subtract a value to both sides of an inequality?
The direction of the inequality remains unchanged. The direction changes when you divide or multiply both sides by a negative number. It also changes if both sides are raised to a negative exponent.
What i the solution to this inequality x- 25 is less than or equal to 33?
Just add 25 to both sides of the inequality - that way, you will isolate the "x", i.e., solve for "x".
What is the inequality to 7n-9 is less than 47?
You would add 9 to both sides, canceling out the 9 on the left. Now you have 7n
What is the solution to this inequality x- 25 is less than or equal to 33?
Add 25 to both sides to give x ≤ 58
What is the solution of the inequality of 3a-2 is greater than 5a-9 clearly showing details of your work?
3a-2 > 5a-9 Subtract 5a from both sides: -2a-2 > -9 Add 2 to both sides: -2a > -7 Divide both sides by -2 and reverse the inequality sign: Solution: a < 3.5 on the number line
What are the properties in solving equations and inequations?
You can add, subtract, multiply, or divide both sides of the equation or inequality by the same number. Don't multiply or divide by zero. In the case of an inequality, if you multiply or divide by a negative number, the sign of the inequality must be reversed. E.g., if you multiply both sides by -2, a "less-than" sign should be replaced by a "greater-than" sign.
What is the inequality of 5n-1 greater or equal to 6?
5n - 1 ≥ 6 Add 1 to both sides: 5n ≥ 7 Divide both sides by 5: n ≥ 7/5 = 1.4
What is 8n-2 is greater then 17n 9?
8n - 2 > 17n + 9 subtract 17n and add 2 to both sides -9n > 11 divide by -9 to both sides and change the symbol of the inequality n < -11/9
-5x 4 greater than -2x 31?
-5x + 4 > -2x + 31 add 2x and subtract 4 to both sides; -3x > 27 divide by -3 to both sides and change the symbol of the inequality; x < 9
Z-3 greater or equal to 25 solve inequality?
In simple cases such as these, you can solve inequalities just like an equation. In this case, you add 3 to both sides.
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.
What is the answer to the inequality of x-1 less than or equal to 2?
X - 1 <= 2 just treat like equation and add 1 to both sides x <= 3
