Question

The sum of two number is 24 and their difference is 10
Find the numbers.​

Answer 1

Answer:

the sum of X and y is 24 in other words X + y = 24 and can be written as equation A

x+y=24

the difference between X and y is 10 in other words x minus y = 10 and can be written as equation B

x-y=10

now solve equation B for X to get the revised equation B

x+y=24

10+y+y=24

10+2y=24

2y =14

y=7

now we know why is 7 which means that we can substitute white for 7 in equation a and solve for x

x+y=24

x+7=24

x=17

hence the proven numbers are 17 and 7
