X= -8
Y= -48
Explanation:
Since we know that 3x-24 is equal to y, we can plug that in for y in the equation 5x-y=8. That would look like 5x-(3x-24)=8. Distribute the -1 and you will get 5x-3x+24=8. Subtract 24 from both sides and get 2x=-16. Divide both by 2 and get x=-8. Than plug in -8 for y in one of the equations to get the y. You will get -48.
The percent change of 13.7 to 40.2 is 193.4%
To find percentage change, you need to find the difference between the two numbers. In this case, 26.5.
You then divide 26.5 by 13.7 and move the decimal point two spaces to the right.

The required solution of the inequality is x < - 6.
Given that,
To solve the equation −2x − 4 > 8.
<h3>What is inequality?</h3>
Inequality can be described as the consideration of the equation including the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Here,
The given equation
−2x − 4 > 8
adding 4 on both sides
-2x > 12
multiply by -1
when multiplying the negative -1 it will change the behavior of the inequality, so.
2x < - 12
Divide by 2 into both sides
x < - 6
Thus, the required solution of the inequality is x < - 6.
