Question

the sum of 2 numbers is 18 and their difference is 6

Answer 1

Answer:

x = 12

y = 6

Step-by-step explanation:

Answer 2

suppose a+b=18 and

a-b=6

therefore, the equations are as follow,

a+b=18 - 1

a-b=6 - 2

(1+2,we get)

2a=24,a=12

therefore put the value instead of 1 no equation,

a+b=18

b=18-a=18-12=6

b=6

Therefore, the numbers are 12,6 respectively.
