Question

Tree times a number increased by 12 is equal to five times the number decreased by 18. Find the number​

Answer 1

Ответ:

15

Объяснение:

let n = number

3n + 12 = 5n - 18

3n-5n = -18-12

-2n=-30

n=15

Answer 2

Let's represent the number you're looking for as "x". The given information can be translated into the following equation:

3x + 12 = 5x - 18

Now, let's solve for "x":

Subtract 3x from both sides: 12 = 2x - 18

Add 18 to both sides: 30 = 2x

Divide by 2: x = 15

So, the number you're looking for is 15.
