There are two numbers. twice the first number minus the second number equals 18. twice the second number minus the first number equals 9. find the numbers

Let's assume

first number is x

second number is y

we are given

Twice the first number minus the second number equals 18

so, we get first equation as

second equation is

Twice the second number minus the first number equals 9

we can solve for y from first equation and plug that in second equation

now, we can plug

now, we can find y

so,

first number is 15

second number is 12..........Answer
