Question

10 added to 3 times a number is equal to 5 subtracted from 8 times a number. What is the number​

Answer 1

Answer:

x=3/2

Step-by-step explanation:

Let The no. be x

3 * x + 10= 8 * x - 5

3x= 8x-5-10

3x= 8x-15

3x+15 = 8x

3x + 15/8 = x

3+15/8 = 2x

18/8 = 2x

9/4 = 2x

9/4*2= x

9/6 = x

3/2 = x

Answer 2

let the number be - x

3 times of number - 3x

10 added to 3 times of number - 3x + 10

A/Q

3x + 10 is equal to :-

8 times of the number - 8x

5 is subtracted from 8 times of the number (8x)

:- 8x - 5

3x + 10 = 8x - 5

10 + 5 = 8x - 3x

15 = 5x

x = 15/5

x = 3

Therefore the number is =3
