Question

The sum of two number is 137 and their differences is 43 find the numbers

Answer 1

Answer:

90,43

Step-by-step explanation:

Sum of 2 number             = X+Y=137      - 1

difference of 2 numbers  = X-Y=43        - 2

X=43+Y                                                     - 3

sub 3 in 1

43+Y+Y=137

2 Y=137-43 =94

Y= 47

THEN X = 90

Answer 2

Let the numbers be x and y

According to the question

x+y=137....(1)

x-y=43......(2)

Adding equations 1 and 2

2x=180

x=90

Subtracting equation 2 from 1

2y=94

y=47

Numbers are 90 and 47
