Question

One number is greater than half of another by 15. If their sum is 48, find the numbers

Answer 1

If one number is x then the second number is 1/2 x + 15

 

their sum is 48

the equation is x + (1/2 x +15) = 48

1.5 x + 15 = 48

1.5 x = 33

x = 22

 

so the numbers are 22 and 26 (1/2 * 22 +15)
