Question

Three times a number is 15 more than twice the same number. Find the number

Answer 1

Answer:

let the number be X

three times a number is 15 =

3 X = 15 + 2x

5 X = 15

X= 15/5

X = 3

Answer 2

Let the Number be y

So,

= 2y + 15 = 3y

= 15 = 3y - 2y

= 15 = y

For Verifying,

2 x 15 + 15 = 3 x 15

30 + 15 = 45

45 = 45

So, the required number is 15
