Question

Find a number whose double is 45 greater than its half
​

Answer 1

Answer:

22.5 is the right answer

Answer 2

Answer:

30

Step-by-step explanation:

let the number be X

double the number means 2x

half the number means X/2

so from question;

2x = X/2 +45

solving 2x-x/2 = 45

(4x-x)/2= 45

3x/2 = 45

3x = 90

X=30
