Explain why solving the equation - 3n - 4 = 2 is different from solving the
Klio2033 [76]

Answer:

Step-by-step explanation:

First get the answer to -3n - 4 = 2

-3n - 4 + 4 = 2 + 4

-3n = 6

n = 6/-3

n = -2

That answer is the only one that is permitted. It is the only one that completely satisfies the equation.

Now when you do the inequality, look what happens.

-3n - 4 < 2              Add 4 to both sides.

-3n-4+ 4 < 2+4

-3n < 6                  Now there are a bunch of ways (2) to solve this.  

                            No matter which way you do it, the arrow will change.

-3n/-3 > 6/-3

n > - 2

That means that any number that is greater than - 2 will satisfy the inequality.

So n = 0 will work. Even n = - 1 will work. Anything bigger than -2 will work. The equation does not provide that kind of latitude.

1 gallon minus 1 quart, 1 pint, and 1 ounce
just olya [345]
16 ounces = 1 pint
2 pints = 1 quart
4 quarts = 1 gallon

1 gallon - 1 quart = 3 quarts
3 quarts - 1 pint = 2 quarts and 1 pint
2 quarts and 1 pint - 1 ounce = 2 quarts and 15 ounces.

Natali5045456 [20]

Answer:

Let's solve your inequality step-by-step.

2y+4>−6

Step 1: Subtract 4 from both sides.

2y+4−4>−6−4

2y>−10

Step 2: Divide both sides by 2.

2y /2 > −10 /2

y>−5

Answer:

y>−5
