Question

there are two numbers that have the sum of 19 and the difference of 3 what are the two numbers

Answer 1

Answer:

let 1st no. be x

and 2nd no. be y

then,

x+y= 19______1

x-y= 3_______2

from equation 2nd we have

x= 3+y_______3

now substitute value of x in equation 1

then we have,

3+y+y=19

3+2y= 19

2y=19-3

y=16/2

y=8

now substitute value of y in equation 3

then we have,

x=3+8

x=11
