Question

the sum of two number is 50 and difference is 60. Find the number
​

Answer 1

Given:

The sum of two number=50

The difference of two number=60

Let

The 1st Number be X

The 2nd Number be Y

To Find

The number

A.T.Q

The Sum of two number=50

==>X+Y=50------(1)

The difference of two number=60

==>X-Y=60------(2)

Adding equation 1 and 2 here

==>X+Y=50

==>X-Y=60

After solving we get here,

==>2X=110

==>X=55

Putting the value of X=55 in EQ 1

==>X+Y=50

==>55+Y=50

==>Y=50-55

==>Y=-5

Hence,

The numbers are 55 and -5

Answer 2

Answer:

x = 55
y = -5

Step-by-step explanation:

Computed by the Equation
x + y = 50________ 1

x - y = 60________ 2

2x = 110

hence x = 55

substituting the values in (1)

55 + y = 50

Hence y = -5
