Yes you are doing it right
Answer:
x = -3
In-Depth Steps:
1.) Start with the bottom equation: 
2.) Set
alone on one side of the equal sign. Your equation will look like
.
3.) Plug
in for
in the first equation. You will get
.
4.) Distribute. Your equation now looks like this:
.
5.) Combine like terms. You will get
.
6.) Subtract 6 from both sides. You get
. We can learn that Y=0.
7.) Go back to either equation and put 0 in for y.
8.) In the top equation, it would look like
and the bottom equation would look like
. We basically got our answer of
, but we will plug it into the
equation, and in-fact, we get x = -3.
Answer: A -22 can be a rational number as well as a integer
Step-by-step explanation:
Whole Number: A whole number is not a fraction or a decimal so a example would be: 43 or 85 or 1 or 3. Zero is not a whole number. Negative are not whole numbers
Rational number: A rational number is a number that can be expressed as a fraction or a decimal. Like 33 can be 33/1. Most numbers are rational. Zero is a rational number.
Integers: A integer is not a fraction or a decimal. its a positive or negative number. Example: 1 or -5 or 85 or -445. there is still some arguments about if zero is a integer.
Irrational numbers: A irrational number cannot be expressed as a ratio. So for example pi: 3.141592653589......(it keeps on going, we haven't even gotten to the end because its infinite).
Natural numbers: Natural numbers are positive numbers. Example: 1,6,3,4,62,3 etc. Sometimes zero is a natural number.

I think its B -34.5<x because x is an unidentified factor and 6/10 is probably greater than this number .
When you divide a fraction by another fraction, it is the same thing as multiplying that fraction by its reciprocal.
The reciprocal is the 'flipped' version of a fraction where the numerator becomes the denominator and the denominator becomes the numerator.
for example, the reciprocal of 9/10 is 10/9
Knowing this information 4/5÷9/10 is the same as 4/5×10/9
Now we can solve...

Answer= 8/9
