Answer 1

Answer:

let the no. be X

5x-10=2x+15

X=25/3

X=8.33

Answer 2

Answer:

the number is 8.33...

Step-by-step explanation:

let the number be x

5x-10=2x+15

collecting like terms

we get 5x-2x=15+10

3x=25

to find x divide the equation by 3

3x/3 is x and 25/3 is 8.33..

hence x=8.333...
