Question

the sum of two numbers is 18 and their difference is 8 find the ratio between the two numbers assuming that the first term is greater than the second

Answer 1

Let the numbers be x and y.

x+y=18
x−y=2

→y=18−x

x−(18−x)=2

x−18+x=2

2x−18=2

2x=20

x=10

∴10+y=18

y=8

Hence, the two numbers are 8 and 10.

Hopefully this helps!
