-4x + 3(2x - 5) = 31 (use distributive property to remove parentheses)
-4x + 6x - 15 = 31 (combine like terms)
2x - 15 = 31 (add 15 to both sides)
+15 +15
2x = 46 (divide both sides by 2)
x = 23
The recursive formula of the sequence is aₙ = aₙ₋₁ - 30
<h3>How to determine the
recursive formula of the sequence?</h3>
From the question, we have the following sequence that can be used in our computation:
67 ,37 ,7, -23, -53
In the above sequence, we can see that the 30 is subtracted from the previous term to get the current term
Using the above as a guide,
So, we have the following representation
aₙ = aₙ₋₁ - 30
The above represents the recursive rule
Hence, the recursive rule of the function is aₙ = aₙ₋₁ - 30

Answer:
Here's a two step equation for example: 4.8y - 6.9 = 3.18
Step-by-step explanation:
How I solve it is using: Sadmep.
wth is that?
Well, it's pemdas backwards. You use this version for solving 2 step equations. But pemdas, not a two step equation.
But, how to solve it: Sadmep..S stands for subtraction...do I see it? Yes! So we are going to do inverse operations..what's the inverse of subtraction..Addition! So you are going to put an addition sign right under the subtraction, and put 6.9..now what you do to one side, you have to do to the other. So add 6.9 to 3.18. Now once you did that, you have to add, but you can't add the 6.9 and the 6.9, you have to cross it out, but you HAVE to hadd 3.18 and 6.9..so do that. So for right now your answer should be: 4.8y = 10.08...let's finish solving! Now since there are two unlike terms, when it comes down to literally this, you have to divide each side by the number with the variable. So: 4.8y divided by 4.8...and 10.08 divided by 4.8.. now remember what I said..4.8y divided by 4.8 are alike so you have to cross it out. But you HAVE to divide 10.08 by 4.8. And once you do that..:::: y = 2.1 ....see? easy and simple!
The answer is -110.
This is because -55-55=-110.
You have to put -55-55 because the question is asking for you to multiply -55 twice, which is technically-55-55.
