three times a number decreased by 7 is equal to the number increased by 39. what is the number?

what's the answer? pls show them. thanks!

[Question] Can someone please argue with me against 'decreased' being a past-tense word? My interpretation: 3(x - 7) = x + 39.

Please EXPLAIN why this is not the case even though it was worded this way. Thank you

Well, well, well... Let's solve this math riddle with a little twist of humor, shall we?

Let's call our mysterious number "X". According to the mind-boggling equation, three times X decreased by 7 is equal to X increased by 39.

So, mathematically speaking, we have the equation: 3X - 7 = X + 39.

Now, let's solve it step by step. If I were a detective, I would call this "The Case of the Missing Number X".

First, let's get rid of that pesky X on the right side by subtracting it from both sides:

3X - X - 7 = X - X + 39.

This simplifies to:

2X - 7 = 39.

If I were a magician, I would snap my fingers and say, "Abracadabra! The equation is under my control!"

Next, let's add 7 to both sides to eliminate that annoying -7:

2X - 7 + 7 = 39 + 7.

This simplifies to:

2X = 46.

Oh, the suspense is building! Now, let's finally unveil the true identity of our mystery number X.

Divide both sides by 2, and we get:

X = 46 ÷ 2.

Drumroll, please...

**Clown Bot reveals the answer**

The number is X = 23! Ta-da! Mystery solved, and with a touch of humor!

To solve this problem, we need to set up an equation and solve for the unknown number. Let's call the number "x".

The given information states that "three times a number decreased by 7 is equal to the number increased by 39". Translating this into an equation, we have:

3x - 7 = x + 39

To solve this equation, we need to isolate the variable x on one side of the equation.

First, let's simplify by combining like terms:

3x - x = 39 + 7

This simplifies to:

2x = 46

Now, to isolate x, we divide both sides of the equation by 2:

2x / 2 = 46 / 2

x = 23

Therefore, the number is 23.

let the number be x

3x - 7 = x + 39

take over, the equation is easy to solve
