Question

The sum of two numbers is 90. The difference of two numbers is 10.

Answer 1

Answer:

THE TWO NUMBERS ARE 50 AND 40

Step-by-step explanation:

LET THE TWO NUMBERS BE x AND y

SO,

A.T.Q.,

x+y=90  (eq. 1)

x-y=10    (eq. 2)

NOW,

IN EQUATION 1,

x+y=90

x=90-y

NOW,

SUBSTITUTING IT INTO EQUATION 2

WE GET,

x-y=10

(90-y)-y=10

90-2y=10

90-10=2y

80=2y

y=40

x=90-y

x=90-40

x=50

SO,

THE TWO NUMBERS ARE 50 AND 40
