Question

the sum of two numbers is 20 and the diffrence is 4

Answer 1

let the two number be X and Y

AND THEIR DIFFERENCE IS = 4

X + Y = 20

X- Y = 4

X+ Y = 20

X- Y = 4

BY SOLVING ABOVE EQUATIONS, WE GET

X = 12 AND Y = 8

GREATER NUMBER IS 12

Answer 2

Step-by-step explanation:

let first no. be x and second be y

x+y=20--1 eq

x-y=4--2 eq

putting x= 4+y in eq1 ( substitution method)

4+y+y=20

2y=20-4

2y= 16

y=16/2

y=8

putting y=8 in eq1

x+8=20

x=20-8

x=12
