The difference of the two numbers is 1.Their sum is 23.find the numbers

11 and 12

Step-by-step explanation:

The two numbers be x and y. The sum of x and y is 23 and the difference is 1.

x + y = 23  

x - y =1

Add the equations

2x = 24

x = 12

y = x - 1

y = 11

i think that you should ask google for the answer to that problem because if we don't know it google does

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .
